Add Telegram file ID caching and reverse geocoding fields

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.
