fix: wire catalog add buttons, fix Trans bold rendering, lint cleanup

- CatalogSearchOverlay: replace handleAddStub with real openAddToCollection/openAddToThread routing based on catalogSearchMode
- ConfirmDialog + __root.tsx: swap t() for Trans component on deleteItemMessage, deleteCandidateMessage, pickWinnerMessage — fixes <bold> rendering as literal text
- Biome format pass: fix 23 lint/format errors across scripts, services, tests
- Planning: mark all UAT and verification gaps resolved for phases 07, 11, 16, 20, 21, 22, 24, 32, 34; close debug sessions
