Replaces the old "Not in lists" filter with "Unused" (no list and no
promotedTo). Adds independent Jokes/Quotes toggles, off by default.
Filter + each toggle persist separately in localStorage. Card scoping uses
:global() so the filter selectors reach FindCard's CSS scope.
Also picks up the editorial-tag picker refactor in FindCard: in-card buttons
now POST to /api/edit-find-tag/ via a single delegated handler instead of
copying slash commands.
