Implement unified error handling system for PACK_IMPORT_PARTENERI

- Add g_last_error package variable matching PACK_JSON/PACK_IMPORT_COMENZI pattern
- Implement get_last_error() and clear_error() functions for VFP orchestrator integration
- Replace exceptions with error storage in validation and main functions
- Return -1 on errors instead of raising exceptions for deferred error handling
- Enable orchestrator to read errors before deciding when to log them
