Subject: [PATCH] bound recording snapshot lookups by segment length

Ordering the recording snapshot and Frigate+ lookups by stream_type ahead of start_time broke index order, so SQLite fetched and sorted every older recording for the camera on each request (about 100 ms on a 30 day camera, run on the event loop). A start_time lower bound of the frame time minus MAX_SEGMENT_DURATION keeps the lookup to a few rows.
