3.06 Template Library Redenumire, Versionare, Multi-format

- Renamed from 'Sabloane Word' to 'Biblioteca Sabloane' (Template Library)
- Multi-format support: Word, Excel, PDF, DWG, Archicad with auto-detection
- Auto versioning: 'Revizie Noua' button archives current version, bumps semver
- Version history dialog: browse and download any previous version
- Simplified UX: file upload vs external link toggle, auto-detect placeholders
  silently for .docx, hide placeholders section for non-Word formats
- File type icons: distinct icons for docx, xlsx, archicad, dwg, pdf
- Updated stats cards: Word/Excel count, DWG/Archicad count, versioned count
- Backward compatible: old entries without fileType/versionHistory get defaults
