- Asset cache now validates entries by comparing stored thumbhash with current
Immich thumbhash instead of using TTL expiration. This makes cache invalidation
precise (only when content actually changes) and eliminates unnecessary re-uploads.
URL-based cache retains TTL for non-Immich URLs.
- Add TELEGRAM_MAX_VIDEO_SIZE (50 MB) check to skip oversized videos in both
single-video and media-group paths, preventing entire groups from failing.
- Split media groups into sub-groups by cumulative upload size to ensure each
sendMediaGroup request stays under Telegram's 50 MB upload limit.

Implement caching for Telegram file_ids to avoid re-uploading the same media.
Cached IDs are reused for subsequent sends, improving performance significantly.
Added configurable cache TTL option (1-168 hours, default 48).
Also added city, state, and country fields from Immich reverse geocoding
to asset data in events and get_assets service.
