Persons & Anwesenheit, Netzwerk & Discovery, Automationen, Einstellungen and
Zugang & Face-ID are now working Livewire pages (were dead "In Kürze" buttons).
Adds persons / discovery_findings / automations tables + models; authorizes the
presence + discovery broadcast channels; silences MQTT debug-log spam. Nav check
10/10 tabs clean (200, 0 console errors, 0 failed requests).
Deeper behaviour (presence polling, discovery sidecar, automation engine) lands
in the respective phase; the pages + schema are in place and render live.
