nixos/home: Separate router storage and uplinks

Browse Source 
Give `river` a dedicated RDMA VF and two RSTP trunk attachments.
Keep client services on the router VIPs and carry Digiweb VLANs
over both switch paths.

Set VF trust, multicast reception, bridge MAC and ARP behavior for
local switching. Wait for Kea interface readiness and apply RSTP
costs through `mstpd` despite port-registration and rename races.

Load `palace`'s RAID module in the initrd. Record RouterOS and
RouterBOOT upgrades and validate port, carrier and switch outages.

Document the deployed architecture, interface handoffs and recovery
procedures. Add physical socket maps, NIC capacities and cable
connections alongside the logical topology and failover checks.

## Networking
Four NICs, all MTU 9000 where jumbo-capable:
| Interface | `palace` attachment | Purpose |
|---|---|---|
| `lan-hi` | `sfh-hi` SR-IOV VF 2 | Box's `hi` assignment and NVMe/RDMA root path; MTU 9000 |
| `ctrs-hi` | `sfh-ctrs` SR-IOV VF 3 | L3-less MACVLAN parent for each container's `host0`; MTU 9000 |
| `ctrs-core` | Virtio via `sfh-core-tap`, `lan-core` and `host-jim` | L3-less MACVLAN parent for UniFi's `lan-core` management attachment |
| `ctrs-lo` | Virtio via `sfh-lo-tap`, `lan-lo` and `host-jim` | L3-less MACVLAN parent for `hass`'s `lan-lo` and the VM's PXE path |
- `lan-hi` — SR-IOV VF 2, the box's own `hi` assignment.
- `lan-hi-ctrs` — SR-IOV VF 3, no L3: the MACVLAN parent for the containers' `hi` interfaces
(`host0` inside each container).
- `lan-core-ctrs` / `lan-lo-ctrs` — virtio NICs (bridged to palace's `lan-core` / `lan-lo`), no
L3: MACVLAN parents for containers that need a `core` or `lo` interface.
The two VFs separate the box's RDMA root traffic from container `hi` traffic; they do not provide
redundant switch paths. The Virtio attachments reach the `jim`-facing `palace` host bridges. Container
`host0` names are intentionally unchanged.
The per-container MACVLAN wiring lives in `systemd.nspawn.*.networkConfig` in
[`sfh/default.nix`](../../../../nixos/boxes/home/palace/vms/sfh/default.nix).
[`sfh/default.nix`](../../../../nixos/boxes/home/palace/vms/sfh/default.nix). The
[`palace` interface topology](../palace.md#end-to-end-interface-topology) traces these interfaces
back through the VM handoffs to the physical switch connections.
