feat(mcp): the UniFi network: WAN, devices, clients, events, alarms and config (#5839)

get_network gives the WAN, clients, Wi-Fi networks, speed tests and devices
by status; list_devices, list_clients (everyone seen, or the newest poll's
top talkers), list_network_events, list_alarms and get_network_config
(networks, port forwards, firewall rules) read what the poller stored.
get_overview names the WAN down while the poll is current, a device offline
or degraded that the controller still reports, and active alarms.
