refactor: Consolidate RFID mapping and add bidirectional pathfinding

Major improvements to AGV navigation system:

• Consolidated RFID management into MapNode, removing duplicate RfidMapping class
• Enhanced MapNode with RFID metadata fields (RfidStatus, RfidDescription)
• Added automatic bidirectional connection generation in pathfinding algorithms
• Updated all components to use unified MapNode-based RFID system
• Added command line argument support for AGVMapEditor auto-loading files
• Fixed pathfinding failures by ensuring proper node connectivity

Technical changes:
- Removed RfidMapping class and dependencies across all projects
- Updated AStarPathfinder with EnsureBidirectionalConnections() method
- Modified MapLoader to use AssignAutoRfidIds() for RFID automation
- Enhanced UnifiedAGVCanvas, SimulatorForm, and MainForm for MapNode integration
- Improved data consistency and reduced memory footprint
