feat(registratura): NAS network path attachments (\\newamun / P:\)

- New nas-paths.ts config: drive mappings, UNC normalization, file:/// URL builder
- RegistryAttachment type extended with optional networkPath field
- 'Link NAS' button in attachment section opens inline path input
- Network path entries shown with blue HardDrive icon + NAS badge
- Click opens in Explorer via file:/// URL, copy path button on hover
- P:\ auto-converted to \\newamun\Proiecte UNC path
- Short display path shows share + last 2 segments
- Validation: warns if path doesn't match known NAS mappings
