feat: wire tracking-config display filters + per-tracker adaptive polling

Display filters (Immich tracking config):
- favorites_only drops events with no favorited new assets, or filters
  added_assets to favorites only
- assets_order_by/assets_order sort the rendered list
  (date / name / rating / random / none)
- max_assets_to_show caps rendered+attached media (default 5 -> 10)
- include_tags strips people from event extras and tags from each asset
- include_asset_details strips city/country/state/lat/lon/is_favorite/
  rating/description; load-bearing fields (thumbhash, file_size,
  playback_size, cache keys) preserved
- New apply_tracking_display_filters helper in dispatch_helpers; wired
  into watcher, webhooks, scheduled/periodic/memory, and manual
  test-dispatch
- Targets sharing a TrackingConfig dispatch together; targets with
  different TCs each see their own shaped event

Adaptive polling:
- Replace NotificationTracker.batch_duration with adaptive_max_skip
- Per-tracker opt-in: NULL/0 disables back-off (every tick runs);
  positive N caps the skip factor at (N-1)-in-N after long idle
- Scheduler caches the cap in module state for the tick fast-path
- Migration adds the new column; API schemas/responses, frontend types,
  i18n, and the tracker form updated to match
