Change ROA settings defaults to NULL and remove obsolete script

Changes:
1. Update settings.ini.example with [ROA] section using NULL defaults
2. Modify ApplicationSetup.prg to handle NULL values properly:
   - CreateDefaultIni writes "NULL" string to INI file
   - LoadSettings converts "NULL" string to VFP .NULL. value
3. Update Oracle package defaults from (0, 1, 2) to (NULL, NULL, NULL):
   - p_id_pol DEFAULT NULL
   - p_id_gestiune DEFAULT NULL
   - p_id_sectie DEFAULT NULL
4. Remove obsolete 02_import_parteneri.sql (replaced by 05_pack_import_parteneri.pck)
5. Update local settings.ini with NULL values

Rationale:
- NULL is semantically correct (no policy/gestiune/sectie specified)
- Previous defaults (0, 1, 2) were invalid IDs in ROA system
- Maintains backward compatibility through Oracle DEFAULT NULL
