Subject: feat(debug): add dry-run mutations mode

New 'Dry-run mutations' toggle in the Debug settings panel blocks
outgoing list updates (the + button) and skips the post-mutation
refresh so optimistic UI changes persist locally for testing. The
mutation gate sits in incrementMediaProgress; CleanAnimeList only
revalidates when the request actually went out.
