fix(commands): enrich search assets, surface variables for all command slots

- UI: command-template-configs now resolves slot variables against the
  active provider first (varsRef[provider_type][slot]) before falling back
  to shared entries, so provider-specific slots like /search, /status,
  /repos, /issues, /boards show the Variables button and autocomplete.
- Backend: /search, /find, /person, /place now normalize raw Immich API
  responses through build_asset_dict, extracting city/country from
  exifInfo and mapping isFavorite -> is_favorite so templates render
  location and favorite indicators.
- Telegram: extract build_telegram_asset_entry into a shared helper so
  the notification dispatcher and command media groups agree on video
  typing and /video/playback URLs; videos no longer render as still
  thumbnails in /latest /random /favorites media mode.
- Commands: send_media_group now reuses the same Telegram file_id caches
  as the notification dispatcher, avoiding re-upload churn for repeated
  commands.
