immich-frame: whole library (last 2y), Ken Burns, weather, 30s interval

Per Viktor: show the whole Immich library from the last 2 years instead of the
single 'china' album, enable Ken Burns pan/zoom, slow the interval to 30s, and
add the weather overlay (London, metric). OpenWeatherMap key is read from Vault
(secret/immich -> frame_weather_api_key), not hardcoded.
