fix(ocr): Improve CUI matching and vendor name extraction

- Add CUI variant matching for Romanian fiscal codes (handles "RO22891860",
  "RO 22891860", and "22891860" formats) in both sync_service and validation
- Fix vendor name extraction to properly handle "SC." prefix (Societate
  Comercială) vs "SC" as staircase in addresses
- Remove problematic TVA pattern that was incorrectly matching percentage values
- Add docTR Plus engine option to dropdown with "(recomandat)" label
