chore(edge): retire the heating-can CAN stack from edge-1

The Viessmann E3 CAN bus is read by vitocal-can, an ESP32 gateway (open3e-esp32)
at the Vitocal's external CAN port, which publishes open3e/# directly to the
cluster broker (S28-28). edge-1 must no longer read the bus: a second UDS
client on the bus disturbs the gateway's requests.

- remove the roles heating-can and socketcan, the play
  install-heating-can.yml, its site.yml import and the inventory group
  heating_can; edge-1 stays in edge_host through zwave_gateway
- install-edge-host.yml pre_tasks: compose down (containers and image) and
  remove /opt/edge-host/heating-can, remove 80-can0.network and reload
  networkd, take can0 down; each step is a no-op where it is already absent
- group_vars edge_host: drop edge_open3e_mqtt_topic, used only by heating-can
- docs: edge-host.md and the ISO README no longer list the CAN stack

@@ -4,6 +4,54 @@ FreeRADIUS terminates EAP-TTLS and proxies the inner PAP request to the
 authentik RADIUS outpost `802.1X Radius`. authentik checks the password and
 the access policy and returns the VLAN.
 
+## Routing by outer identity
+
+FreeRADIUS decides on the outer EAP identity (`User-Name`) of each request,
+before any local EAP processing:
+
+| Outer identity | Path |
+|---|---|
+| `anonymous` or `anonymous@<anything>` (any case) | EAP-TTLS terminated in FreeRADIUS, inner PAP to authentik |
+| anything else | whole EAP conversation (all rounds, `State` included) proxied to the UDM RADIUS for UniFi Endpoint accounts |
+
+UniFi Endpoint clients send their real account name as outer identity; their
+names look like ordinary usernames, so the rule cannot match on name patterns.
+The UDM's Access-Accept/Reject/Challenge goes to the NAS unchanged, including
+its Tunnel-* VLAN and MS-MPPE keys. The "Accept without VLAN is rejected" rule
+applies to the authentik path only. Accounting is answered locally on both
+paths.
+
+The anonymous outer identity is mandatory for authentik clients: without it
+the login goes to the UDM and fails.
+
+UDM target: home server `udm`, `10.2.11.1` UDP 1812 (the UDM on VLAN 11,
+UniFi network "(11) RADIUS"), shared secret `UDM_RADIUS_SECRET` from OpenBao
+`apps/radius`. The UDM RADIUS accepts clients from `10.2.11.0/24` only, not
+from the pod CIDR.
+
+### Path to the UDM
+
+Each FreeRADIUS pod has a second interface `net1` on VLAN 11
+(NetworkAttachmentDefinition `freeradius-udm`,
+`kubernetes/apps/authentik/freeradius-network-attachment.yaml`):
+
+- macvlan on the node link `radius0` (VLAN 11 on `uplink`, no host addresses;
+  VLANConfig in `kubernetes/talos/patches/k8s-{1,2,3}.yaml`). VLAN 11 is in
+  Cilium's `bpf.vlanBypass`, otherwise the tagged frames are dropped on
+  `uplink`.
+- IPv4 leased from the UDM DHCP server (cni-dhcp-daemon), requested without
+  the routers option: `net1` holds only the connected `10.2.11.0/24`, no
+  default route. The proxy socket is not bound to an address; the kernel's
+  route lookup for `10.2.11.1` picks `net1` and its leased address as source.
+- IPv6 disabled on `net1` (VLAN 11 sends router advertisements).
+- The NAS listeners are bound to `eth0` (`interface = eth0`); nothing listens
+  on `net1`.
+- Traffic on `net1` bypasses Cilium; there is no CNP for the UDM hop.
+
+`radius0` must exist on every node before FreeRADIUS pods are scheduled
+there: without it the macvlan ADD fails and the pod stays in
+`ContainerCreating`.

+Setup page: `https://wlan.renner.uno` (behind the Authentik gate, any
+authentik user), served by the Go service `wlan-setup/`
+(`kubernetes/apps/authentik/wlan-setup*.yaml`). Android, Apple and Windows get
+Passpoint profiles with their own app password; Linux an `nmcli` command
+(NetworkManager has no Passpoint support) that carries no password.
+
+Passpoint: `/<platform>/install` (`android`, `apple` or `windows`) signs the
+user in through the authentik OAuth2 application `wlan-setup` (scope
+`goauthentik.io/api`). On `/<platform>/callback`, the service exchanges the
+code, creates an app password (`wlan-<platform>-<user>-<timestamp>-<random>`)
+with the user's own access token, and hands out the profile:
+
+- Android: `application/x-wifi-config` in the response to that GET, as its
+  installer requires.
+- Apple: a `.mobileconfig` download.
+- Windows: a CarrierProvisioning XML signed with XML-DSig (enveloped, C14N
+  1.0, rsa-sha1, chain in KeyInfo) by the Let's Encrypt certificate
+  `wlan-setup-signing`; kept for 5 minutes under a single-use token. The
+  browser is sent to `ms-settings:wifi-provisioning?uri=https://wlan.renner.uno/windows/profile/<token>`;
+  Windows Settings fetches it (Ingress `wlan-setup-provisioning`, without the
+  gate) and offers "Add".
+
+The service stores nothing else. Deleting the app password in authentik removes
+that device from the WLAN. The profiles match WLANs that advertise Hotspot 2.0
+with domain and NAI realm `renner.uno` (EAP-TTLS/PAP), i.e. "Renner UniFi".
+Creating the app password needs no admin rights.
+
+App passwords expire when unused. The page creates them with 29 days (the API
+caps new tokens at 30 days unless the group attribute
+`goauthentik.io/user/token-maximum-lifetime` allows more). Every 802.1X login
+with an app password renews it to 60 days: the policy
+`dot1x-app-password-renew` on the `dot1x-login` binding (at most one write per
+day). authentik rejects expired app passwords and deletes them in its
+`clean_expired_models` task. A device that has not connected for 60 days, or a
+profile that was never installed, loses its app password and needs a new
+profile from the page.
 
 All clients use EAP-TTLS with inner PAP. The server certificate is a public
 Let's Encrypt certificate for `radius.renner.uno`, so no CA needs to be
