Move the port inspector onto device pages

Replace the all-switches Inspector page with a per-device front panel,
port table and detail panel. /inspector now redirects to the dashboard,
and /device/<name>#port-<n> links directly to a port.

Restore neighbor names after UniFi's LLDP change: read local_port_idx
and resolve neighbors by MAC using Prometheus NIC data, UniFi devices
and the wired client table. This also brings back Run Diagnostics on
server ports, which depends on a named neighbor.
