fix: merge upstream, fix locale duplicate, add missing catalog deps

- Merged upstream/main (MakerKit latest fixes)
- Fixed locales.tsx: removed hardcoded 'de' duplicate (defaultLocale already = 'de')
- Added missing pnpm catalog entries for custom packages:
  @measured/puck, @react-pdf/renderer, @tiptap/*, exceljs, iban, papaparse
- CACHE_BUST=7 for full rebuild
