Code-review follow-ups:
- Validate the raw submitted value before apply_values coerces it, in both
the single-edit and bulk endpoints — a scalar set onto a tags field now
rejects (422 / rejected) instead of silently char-splitting into a list.
- Catalog prunes bulk selections to the currently-visible (filtered) entries
after each list fetch, so the bulk bar can't act on rows the user has
filtered out of view.
