feat(34-02): extract hardcoded strings from modals, routes, and catalog

- AddToCollectionModal: all labels, placeholders, toast messages
- collection/index.tsx: tab labels (Gear/Planning)
- threads/$threadId/index.tsx: thread detail page and AddCandidateModal
- items/$itemId.tsx: back links, action buttons, field labels, metadata
- setups/$setupId.tsx: all setup detail strings and confirm dialog
- users/$userId.tsx: public profile page strings
- global-items/index.tsx: discover/catalog filter UI strings
- Added catalog.json namespace (en + de) and registered in i18n.ts
- Extended en/de threads, setups, collection, common locales with missing keys
