fix(talos): give nodes an IPv6 InternalIP from the mgmt ULA

cilium-health reports 0/3 reachable on every node, with Node 1/2 and
Endpoints 2/2 — exactly one of the two node probes fails, including
against localhost.

The Node objects carry only InternalIP=10.2.40.x, because kubelet's
nodeIP.validSubnets lists only the IPv4 mgmt subnet. With no IPv6
InternalIP to take from the Node object, Cilium falls back to detecting
the node's IPv6 from mgmt0 and picks the SLAAC address derived from the
dynamic provider prefix. It records that in CiliumNode and probes it
until the agent restarts, so a prefix change leaves every agent probing
an address that no longer exists:

  cilium-health:  2003:d6:9718:3b02:5a47:caff:fe74:7027
  mgmt0 now:      2003:d6:9713:b202:5a47:caff:fe74:7027

The interface identifier is the same EUI-64; only the prefix moved. This
is not a one-off — the prefix was 2003:d6:9744:4802 in May and
2003:d6:9718:3b02 in August.

The GUA was never meant to be a control-plane address; that is what the
ULA is for, and BGP already peers on fd40::/64. Listing it in
validSubnets gives the Node a stable IPv6 InternalIP, which Cilium then
uses in preference to its own detection — the same path that already
makes CiliumNode's IPv4 InternalIP agree with the Node object.

Verified fd40::/64 SLAAC addresses are present on mgmt0 on all three
nodes, so no node is left without an address in a listed subnet.

The data path is unaffected either way: Endpoints probes are 2/2 and
conntrack is clean. What this fixes is the health signal, which is
permanently red today and therefore useless for spotting a real outage.

+Terminus (self-hosted TRMNL BYOS server) plus the headless renderer that
+screenshots the Home Assistant entrance dashboard and pushes it in. One
+device: a TRMNL X at the entrance, 1872x1404, 16 greys.
+
+## Device firmware
+
+Terminus mirrors one model-agnostic binary and it is the **ESP32-C3** (OG)
+build. This panel is a TRMNL X, i.e. ESP32-S3, so that file is not the
+artefact for a manual flash here. Use
+`https://trmnl-fw.s3.us-east-2.amazonaws.com/trmnl_x/flash/FW<version>.bin`
+— a merged image at offset `0x0` — and run `esptool image-info` on
+anything before writing it.
+
+The panel runs 1.8.16, flashed over USB on 2026-09-05. It shipped on
+1.8.6, where turning on `firmware_update` froze the screen for as long as
+an update was offered (fixed upstream in 1.8.7, commit `9b7a0f7`).
+
+## Image automation
+
+Both images are enrolled (`infrastructure/image-automation/terminus.yaml`,
+`trmnl-renderer.yaml`) and track the latest `0.x`. A bad bump on either
+surfaces as a **blank or corrupted panel**, not as a failed rollout — no
+readiness probe can tell that a rendered screen became unreadable. Look at
+the panel after a bump lands; revert the tag if it is wrong.
+
+## Device endpoint
+
+`trmnl-device.renner.uno` is the device-facing name, TLS via Traefik
+(`device-ingress.yaml`). `API_URI` must carry the same scheme the device
+polls with, because Terminus bakes it into the absolute `image_url` it
+returns. The LoadBalancer in `device-service.yaml` keeps `10.2.99.89`
+without a hostname as a cleartext fallback that depends on neither

-- `ghcr.io/usetrmnl/terminus` — publishes a usable `0.x.0` tag stream, so
-  unlike the three above this is **not** a tag-format problem. It is left
-  unenrolled because the blast radius is hardware: Terminus is pre-1.0,
-  cuts no GitHub Releases and ships no changelog, and it serves the
-  firmware and `/api/display` contract that the TRMNL X panel polls. An
-  unattended bump that changes either can leave a wall-mounted device
-  dark, with no rollback path that doesn't involve the captive portal.
-  Bumps are a reviewed, manual act: read the commit range, then edit the
-  tag in `kubernetes/apps/trmnl/terminus.yaml` (both containers).
-
-  The Valkey sidecar alongside it *is* enrolled (`valkey.yaml`) — it holds
-  only the Sidekiq queue and touches no device-facing contract.
-
-- `ghcr.io/usetrmnl/trmnl-ha-amd64` — the TRMNL screenshot renderer, for
-  the same reason and one more. It owns the dithering pipeline and the
-  webhook payload shape, so a bad bump surfaces as a *corrupted or blank
-  panel*, not as a failed rollout — there is no readiness signal that
-  catches "the image is now unreadable". Separately, upstream publishes
-  **no multi-arch manifest**: only the arch-suffixed `trmnl-ha-amd64` and
-  `trmnl-ha-aarch64` repositories exist, so an ImagePolicy here would also
-  be pinning us to one architecture in a way the tag does not make
-  obvious. Bump manually in `kubernetes/apps/trmnl/renderer.yaml`.
+Only a tag-format problem belongs on that list. The policy is to run the
+latest version and let image-automation hold us there wherever the tags
+allow it, so an image with a usable semver stream gets enrolled even when
+a bump carries risk. Where a bad bump is hard to detect, the answer is a
+note about what to check afterwards — see `apps/trmnl/README.md` for the
+panel, whose failure mode is a blank screen rather than a failed rollout
+— not an exclusion.
