fix(registratura): prevent duplicate numbers, add upload progress, submission lock, unified close/resolve, backdating support

- generateRegistryNumber: parse max existing number instead of counting entries
- addEntry: fetch fresh entries before generating number (race condition fix)
- Form: isSubmitting lock prevents double-click submission
- Form: uploadingCount tracks FileReader progress, blocks submit while uploading
- Form: submit button shows Loader2 spinner during save/upload
- CloseGuardDialog: added ClosureResolution selector (finalizat/aprobat-tacit/respins/retras/altele)
- ClosureBanner: displays resolution badge
- Types: ClosureResolution type, registrationDate field on RegistryEntry
- Date field renamed 'Data document' with tooltip explaining backdating
- Registry table shows '(înr. DATE)' when registrationDate differs from document date
