Add configurable ROA settings (IdPol, IdGestiune, IdSectie) to VFP integration

Implement global configuration for ROA system IDs via settings.ini:

VFP Changes:
- Add [ROA] section to settings.ini with IdPol, IdGestiune, IdSectie
- Update ApplicationSetup.LoadSettings to read ROA configuration
- Update ApplicationSetup.CreateDefaultIni with default values (0, 1, 2)
- Modify sync-comenzi-web.prg to pass ROA settings to Oracle package

Oracle Package Changes (06_pack_import_comenzi.pck):
- Add optional parameters to importa_comanda signature with defaults
  * p_id_pol (default: 0)
  * p_id_gestiune (default: 1)
  * p_id_sectie (default: 2)
- Remove hardcoded constants (c_id_pol, c_id_sectie, c_id_gestiune)
- Update PACK_COMENZI.adauga_comanda call to use p_id_sectie parameter
- Update PACK_COMENZI.adauga_articol_comanda to use p_id_pol and p_id_sectie

Benefits:
- Flexible configuration without code changes
- Maintains backward compatibility with default values
- Centralized ROA system configuration
