Implement complete property and label storage for nodes
- Added update_node method to Graph for safe node modifications
- Added schema lookup methods to convert IDs back to names
- Fixed node creation to properly store labels and properties
- Fixed node retrieval to return labels and properties correctly
- Support for all property types: strings, integers, floats, booleans
- Nodes now correctly store and retrieve: labels and properties as documented
Verified working with test:
- Created node with labels ["Person", "Employee"] and mixed properties
- Retrieved node showing all data stored correctly
