list_unscanned_candidates pulled every hashed image_exif row, including
videos. filter_excluded then dropped them client-side without writing a
marker, so the same set re-appeared every watcher tick — emitting the
"backlog drain — running detection on N candidate(s)" log forever and
producing no progress.
face_stats.total_photos counted the same video rows in the denominator,
so the SCANNED percentage was structurally capped below 100%.
Add an image-extension SQL predicate (case-insensitive, sourced from
file_types::IMAGE_EXTENSIONS) and apply it to both queries. Videos
never enter the candidate set, total_photos counts only what can
actually be scanned, and 100% becomes reachable.
