feat: Add support for Frigate reviews / detections [initial PR] (#2315)

- Add support for Frigate reviews / detections.
 - Add support for GenAI metadata.
- Significant internal refactor to more flexible "UnifiedQuery" to allow
mixing cameras with simple metadata and review metadata (e.g. a timeline
view of a Frigate camera with reviews, and a Reolink camera with simple
metadata).
 - Add support for folder media as camera media.

There are a few more PRs to commit prior to this going live, but
commiting this for now due to the scale of the change.

BREAKING CHANGE: `media_type` and `events_type` are retired under
`live`, `viewer` and `timeline` configuration sections, instead media
type is associated (once) with the camera under `media`.
