Wireless RF Health (fleet Wireless page + per-AP Radios tab):
- Channel usage map across 2.4/5/6 GHz with co-channel overlap; operating
channel resolved live from /interface/wifi/monitor on the wifi package
(auto-channel radios report no frequency in /print).
- AP deployment density: client RSSI distribution on the -90..-30 dBm scale
with a coverage-gap warning.
- AP radio TX retries histogram (0%->35%+) with band selector, derived from
per-client CCQ (new wireless_radio_quality InfluxDB series).
- WiFi connectivity success funnel (Association/Auth/DHCP) derived from logs.
Per-port connected clients (Ports tab):
- New card lists clients physically connected to a selected port (host/MAC/
IP/VLAN/connection time, linked to client pages).
- Distinguishes physical clients from the raw MAC table: uplink/trunk ports
are auto-detected (topology neighbor, multi-VLAN MAC spread, or high MAC
count) and show an uplink explainer + "view MAC table" disclosure instead
of every reachable MAC.
- Added clients.first_seen ("connected since"); set once, preserved across polls.
