Remove-from-catalog: a third durable curation store

Titles that aren't games (misread box art, out-of-scope items) can now
be removed outright: a danger button in the catalog's edit panel posts
/api/remove-title, which drops the line's matches rows (veto'd ones
too — removal is the human explicitly discarding the line), records the
decision photo-scoped in data/title_removals.json, and replays
titles.json. Every rebuild filters removed sightings after edits and
before dedupe, so re-extraction cannot resurrect them; undo by deleting
the record from the store. The three stores now share one scoped-record
parser and recorder.
