backfill_utc_dates refused any fs_time re-resolution of a tag-dated row,
assuming exiftool had failed on the file. Files whose date tags are all
0000:00:00 (e.g. uv-prod-long.mp4) were read fine and simply have no
date, so they sat unconverted and re-ran through exiftool every tick.
resolve_dates_batch_report now also returns the paths exiftool read
without error (-Error surfaces ExifTool:Error in the JSON). The drain
lets fs_time stand for an exiftool-legacy row only when exiftool read
the file; read errors / missing entries and kamadak exif-legacy rows
keep refusing.
