- POST /image/tags/bulk { file_names, add: [names], remove: [ids] }: one
transaction over many photos; names match case-insensitively and are
created when missing; 400 if a tag is both added and removed.
- Adding a tag a photo already has is a no-op (was a 500 on
UNIQUE(rel_path, tag_id)).
- Adding a tag no photo carries reuses it (the lookup only saw tags in
use, so create_tag hit idx_tags_name_nocase: 500). update_tags could
likewise skip such ids silently.
- Removing a tag matches the name case-insensitively and deletes it from
every path sharing the photo's content, as reads union them; it used to
answer 200 and leave the tag on the other copy.
- update_tags returns errors instead of panicking with the TagDao lock
held, which poisoned it for every later tag request.
