fix: RFID duplicate validation and correct magnet direction calculation

- Add real-time RFID duplicate validation in map editor with automatic rollback
- Remove RFID auto-assignment to maintain data consistency between editor and simulator
- Fix magnet direction calculation to use actual forward direction angles instead of arbitrary assignment
- Add node names to simulator combo boxes for better identification
- Improve UI layout by drawing connection lines before text for better visibility
