feat(monitoring): add a disk health dashboard

Throughput, IOPS, mean operation latency, utilisation, queue depth and
controller temperature for all nine NVMe drives, plus Ceph's own OSD latency for
comparison against the block layer.

Every panel joins node_disk_* to node_nvme_info and node_uname_info rather than
plotting the device name. That is not decoration: nvme0 is the Kingston system
disk on k8s-1 and k8s-3 and the Crucial on k8s-2, so a legend keyed on the
device compares different hardware across nodes and does so silently. The
inventory table resolves the OSD column through ceph_disk_occupation for the
same reason — it follows Rook instead of restating a device list that goes stale
the next time a drive is swapped.

Every expression was run against Prometheus before being written into the JSON,
which is also how the caveats in the panel descriptions were found. Latency is
accumulated-time over completed-operations, so it is a mean with no tail and it
vanishes while a device is idle: absence of traffic, not absence of a problem.
Utilisation near 100% on NVMe does not mean saturation the way it does on a
spindle, which is why queue depth shares that panel.

Temperature is the only SMART-adjacent value present, because it is the only one
the kernel publishes through sysfs. Wear, written-bytes totals, power-on hours
and media errors need an NVMe admin ioctl and no exporter here produces them
(#549). The dashboard says so in a panel rather than letting a green screen imply
a healthy drive.

That gap is worse than #549 describes, and the note records why. The Crucial P3
drives were retired from Ceph because they were worn, and now carry the
EPHEMERAL volume — so the drives with the least endurance left are the ones
holding container state, and they are the ones nothing watches. The measured
write latency already separates them from the Samsung OSDs by more than an order
of magnitude.

Also fixes the add-a-dashboard instructions above the generator, whose third
step told the reader to tick a row off ../DASHBOARD-MIGRATION.md. That file does
not exist anywhere in the repo, so the step could not be followed.

+# Proposal — separate the four traffic classes onto their own VLANs
+
+Status: draft. The question this started with is **answered** — from the Cilium
+source and flag reference, not from a test — and the answer changes the shape
+of the proposal rather than confirming it.
+
+Supersedes the framing in issue #576, which described this as "give node
+management its own NIC, and Ceph public its own VLAN". That was two of four
+classes and one of them turned out already solved.
+
+## The four classes
+
+| class | what it is | where it goes today |
+|---|---|---|
+| **Ceph replication** | OSD-to-OSD heartbeat, replication, recovery | VLAN 49, its own X710 port — **separated** |
+| **cluster-internal** | pod-to-pod east-west, including Ceph client I/O | pod network, VXLAN over `mgmt0` |
+| **cluster-external** | ingress to LoadBalancer VIPs, egress to LAN and internet | `mgmt0` |
+| **management** | Talos API, etcd, kube-apiserver, kubelet | `mgmt0` |
+
+Three of four share one interface. That is not a design decision — until the
+bare-metal conversion there was one NIC to work with.
+
+Ceph client I/O living on the pod network is correct rather than a leftover:
+that traffic *is* cluster-internal. Ceph is done.
+
+## Principle
+
+**Each class gets its own VLAN. Which physical interface a VLAN lands on is a
+separate, changeable decision.**
+
+Defining classes by VLAN means the separation survives recabling, port failures
+and capacity changes, and it does not require one port per class. Defining them
+by interface would freeze a capacity decision into the architecture.
+
+## The finding that shapes everything else
+
+The original open question was whether `nodePort.directRoutingDevice` moves the
+next-hop of Cilium's direct routes, or only selects an interface. It is
+answerable from the source, and the answer is: **only the interface.**
+
+`installDirectRoute` takes the next-hop as a parameter:
+
+```go
+func installDirectRoute(log *slog.Logger, prefix netip.Prefix, nodeIP net.IP,
+    skipUnreachable bool) (routeSpec *netlink.Route, err error)
+```
+
+and `nodeUpdate` supplies it as `newNode.GetNodeIP(false)`. `GetNodeIP` returns,
+in priority order, `NodeInternalIP` → `NodeExternalIP` → anything else. The
+same `newIP4` is what tunnel mode uses as the VXLAN endpoint.
+
+`NodeInternalIP` comes from the Kubernetes Node object. `--ipv4-node` looks like
+an override but is not one: `initFromConfig()` calls `SetNodeInternalIP` and
+`initFromK8s()` runs **after** it and overwrites the value. In a Kubernetes
+cluster there is no path by which Cilium's node IP differs from the kubelet's
+`InternalIP`.
+
+`--direct-routing-device` is documented as "Device name used to connect nodes in
+direct routing mode" — a device, not an address.
+
+**So cluster-internal traffic is welded to the node IP, and the node IP is the
+kubelet InternalIP.** Two consequences:
+
+- The class cannot be moved off whatever VLAN the node IP lives on.
+- **Routing mode is irrelevant to this problem.** Tunnel mode sources the VXLAN
+  from the node IP; native mode uses it as the direct-route next-hop. Native
+  routing buys nothing here, so the disruptive, non-rolling step this proposal
+  previously contained is simply gone.
+
+## Consequence: draw the line the other way
+
+If cluster-internal cannot leave the node IP, then separation has to come from
+moving *management services* off it — and each one has to be checked
+individually, because they do not share a mechanism.
+
+| management service | can it leave the node IP? | lever |
+|---|---|---|
+| etcd | **yes** | `cluster.etcd.advertisedSubnets` (+ `listenSubnets`, which defaults to it) |
+| kube-apiserver endpoint | **yes** | already a VIP — `Layer2VIPConfig` with a `link:` field |
+| Talos API | **n/a** | `apid` answers on every node address (measured); a client and firewall choice, not a bind setting |
+| kubelet | **no** | it *is* the node IP, by definition |
+
+So four VLANs are reachable, but the boundary does not fall where the class
+names suggest: **kubelet stays with cluster-internal.** That is the honest
+result, and it is worth stating plainly rather than filing kubelet under
+management and hoping.
+
+The remaining classes keep the levers established earlier:
+
+- **cluster-external ingress** — `CiliumBGPNodeConfigOverride.spec.bgpInstances[].peers[].localAddress`.
+  For eBGP the session source is the next-hop, so pinning the session pins
+  where return traffic arrives. The session to the UDM has been running for
+  months.
+- **cluster-external egress** — eBPF masquerading follows the output device, so
+  this is a default-route decision plus `enable-masquerade-to-route-source`
+  (today `false`).
+- **Ceph replication** — Multus macvlan on VLAN 49, done.
+
+## The general escape hatch
+
+Ceph is separated because its OSDs got a second interface and stopped using the
+pod network for replication. That is the *only* mechanism that fully detaches a
+workload from the node IP, and it generalises: anything that must not ride the
+node IP gets its own `NetworkAttachmentDefinition`.
+
+It is also expensive per workload — an attachment, an IPAM pool, a pod spec
+change. Worth it for Ceph replication. Not worth it for east-west traffic in
+general.
+
+## Recommended mapping
+
+Two ways to arrange this, and they differ only in which VLAN gets relabelled:
+
+**A — move the node IP to a new cluster VLAN.** VLAN 40 keeps etcd, the API VIP
+and Talos API. Cleanest match to the class names, but it changes every node's
+identity, which is the one address the whole cluster is administered through.
+
+**B (recommended) — leave the node IP on VLAN 40 and move management off it.**
+VLAN 40 becomes the cluster VLAN; a new VLAN carries etcd and the API VIP.
+Identical end state, and no node ever changes its InternalIP.
+
+Under B:
+
+| VLAN | carries |
+|---|---|
+| 49 | Ceph replication |
+| 40 (relabelled *cluster*) | pod east-west, kubelet |
+| new *management* | etcd, kube-apiserver VIP, Talos API by convention |
+| new *external* | LoadBalancer ingress, egress default route |
+
+The property the user asked for — management carries only management traffic —
+holds under B. The label moves; the property is what matters.
+
+## Migration shape
+
+Every step is rolling and reversible. The routing-mode change is gone.
+
+1. **New VLANs** on the switch, trunked to the X710. Nothing uses them.
+2. **Addresses** on the new VLANs via Talos, one node at a time, `--mode=try`.
+   Still unused; this only proves the L2 works.
+3. **etcd** to the management VLAN via `advertisedSubnets`. One node at a time,
+   waiting for a healthy quorum between each.
+4. **API VIP** to the management VLAN via `Layer2VIPConfig.link`. DNS for
+   `k8s.renner.uno` follows.
+5. **cluster-external**: BGP `localAddress`, default route, masquerade flag.
+   Reversible by reverting the override; failure is visible immediately in
+   `cilium-dbg shell -- bgp/peers`.
+6. Verify VLAN 40 by what is *absent* from it, not by what still works.
+
+Step 3 is the one that deserves care — etcd is the only step where a mistake
+costs quorum rather than connectivity.
+
+## What this does not buy
+
+Management currently shares a 10 Gb link and is not contended. Nothing observed
+today is slow because of this. The case for the split is that traffic classes
+with different failure modes and security postures should not be
+indistinguishable — not that something is broken.
+
+## Sources and measurements
+
+Source, Cilium v1.20.1 (the running version):
+
+- `pkg/datapath/linux/node.go` — `installDirectRoute(…, nodeIP net.IP, …)`,
+  fed from `newIP4 = newNode.GetNodeIP(false)`; `createDirectRouteSpec` rejects
+  a next-hop that is not directly reachable.
+- `pkg/node/types/node.go` — `GetNodeIP` prefers `NodeInternalIP`.
+- `pkg/node/sync/local_node_sync.go` — `initFromConfig()` applies
+  `--ipv4-node`, `initFromK8s()` runs afterwards and overwrites it from the
+  Kubernetes Node.
+- `cilium-agent` flag reference — `--direct-routing-device`: "Device name used
+  to connect nodes in direct routing mode".
+
+Talos:
+
+- Multihoming guide — `cluster.etcd.advertisedSubnets`; `listenSubnets`
+  defaults to it. kube-apiserver and Talos API listen addresses are not
+  covered there.
+- `kubernetes/talos/patches/k8s-{1,2,3}.yaml` — `Layer2VIPConfig` for
+  `10.2.40.60` with `link: mgmt0`.
+
+Measured on the cluster:
+
+- `apid` answered on a node address that is not the InternalIP, so the Talos
+  API is not bound to one address.
+- k8s-1 currently holds one routable v4 address plus the VIP on `mgmt0`; its
+  InternalIP had changed since the last session, which is why nothing here
+  names an address as fixed.
+- Cilium runs `routing-mode: tunnel` with `enable-masquerade-to-route-source`
+  unset and no direct-routing device configured.
+
+Not verified: whether the kube-apiserver's `--advertise-address` follows the
+node IP independently of the VIP. It does not affect the recommendation, since
+clients reach the API through the VIP either way.

Tracked as **#549** — do not read a healthy dashboard as a healthy drive.\n\n**The three roles are not interchangeable.** Each node carries a Kingston OM8PGP41024Q as the Talos system disk, a Samsung PM983 that Rook claims as the Ceph OSD, and a Crucial P3 that was retired from Ceph and now carries the EPHEMERAL volume. The Crucial drives were replaced *because* they were worn, so the drive with the least endurance left is the one holding container state — and it is the one nothing is watching.\n\n**Device names are not identity.** `nvme0` is the Kingston on k8s-1 and k8s-3 and the Crucial on k8s-2. Every panel here resolves the model through `node_nvme_info` for that reason; a query written against a bare device name compares different hardware and will keep doing so silently.",
