fix: doc type persistence on edit + filter deadlines by document type

- Fix doc type showing "altele" after edit: preserve initial documentType
  in allDocTypes map even if not in defaults or Tag Manager
- Filter deadline categories by document type: only cerere/aviz unlock
  full permitting categories (CU, avize, urbanism, autorizare)
- Other doc types (scrisoare, notificare, etc.) only get completari +
  contestatie as deadline categories
- Add completari to intrat direction (was missing)
- Pass documentType to DeadlineAddDialog for category filtering
