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.

+
+    Shared by the notification dispatcher and provider command handlers so
+    both paths agree on media typing, URL rewriting, and auth headers. In
+    particular: video assets MUST be typed ``"video"`` and point at a real
+    video endpoint (e.g. Immich ``/video/playback``) — if they are sent as
+    ``"photo"`` pointing at a thumbnail URL, Telegram delivers a still image
+    for every video in a media group and the user sees a dead poster frame
+    instead of a playable clip.
+
+    Args:
+        url: Source URL for the asset bytes. Prefer a transcoded/preview
+            URL for videos (``/video/playback``) and a preview-sized
+            thumbnail for photos.
+        media_type: Case-insensitive type token. Accepts ``"video"``/
+            ``"VIDEO"``/``MediaType.VIDEO`` or any photo-like string.
+        api_key: Optional API key. Attached as ``x-api-key`` iff the URL is
+            served by one of the provider hosts in ``internal_url`` /
+            ``external_url`` (prevents leaking the key to unrelated hosts).
+        internal_url: LAN-facing provider URL. Used to rewrite
+            ``external_url`` prefixes so Docker-host downloads stay on the
+            LAN instead of egressing to the public domain.
+        external_url: Public provider URL the notification URL was built
+            from. Only used for the LAN rewrite and the api-key scope check.
+        cache_key: Optional explicit cache key. Providers whose URLs don't
+            embed a stable asset id (Google Photos) pass one through so the
+            file_id cache still works.
+
+    Returns ``None`` iff ``url`` is empty.
