Ben Stull 7886840362 fix(slice5): validate raw metadata input + prune stale bulk selections
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.

"""§22.4a SLICE-4/5 — entry metadata edit endpoints.
`POST .../rfcs/<slug>/meta` writes schema-defined metadata to an entry's sidecar
with a direct commit (D7: direct commit for authorized roles), validated against
the collection's field schema at the write boundary (INV-4), lazy-migrating a
legacy entry to a clean body-only `.md` on first edit. The Owner-gated
`metadata.migrate_collection` operator endpoint also lives here (SLICE-4 carried
work); SLICE-5's bulk endpoint will join it.
