Add quiet hours, fix Telegram bugs, and improve cache performance

- Add quiet hours support to queue notifications during configured time windows
- Fix UnboundLocalError when single-item document chunk exceeds max_asset_data_size
- Fix document-only multi-item chunks being silently dropped (missing skip guard)
- Fix notification queue entity lookup by storing entity_id in queued params
- Fix quiet hours using OS timezone instead of HA-configured timezone (dt_util.now)
- Fix chat_action schema rejecting empty string from "Disabled" selector
- Fix stale thumbhash cache entries not being removed on mismatch
- Fix translation descriptions for send_large_photos_as_documents
- Add batch async_set_many() to TelegramFileCache to reduce disk writes
- Add max-entries eviction (2000) for thumbhash cache to prevent unbounded growth
- Eliminate redundant _is_asset_id/get_asset_thumbhash lookups in media group loop
