[2ff88f42] feat(connector-superoffice): Implement Company Explorer sync and Holiday logic

- **Company Explorer Sync**: Added `explorer_client.py` and integrated Step 9 in `main.py` for automated data transfer to the intelligence engine.
- **Holiday Logic**: Implemented `BusinessCalendar` in `utils.py` using the `holidays` library to automatically detect weekends and Bavarian holidays, ensuring professional timing for automated outreaches.
- **API Discovery**: Created `parse_ce_openapi.py` to facilitate technical field mapping through live OpenAPI analysis.
- **Project Stability**: Refined error handling and logging for a smooth end-to-end workflow.
