fix(registratura): NAS links copy to clipboard instead of broken file:///

Browsers block file:/// URLs from web pages for security. Changed:
- Detail sheet: click on NAS attachment copies path to clipboard with
  'Copiat!' green badge feedback. Full UNC path shown below.
- Entry form: NAS link click = copy path (removed window.open fallback)
- Removed unused toFileUrl/toFileUrlByIp imports from form
- User pastes in Explorer address bar to open the file
