Implement dynamic admin configuration system for NocoDB settings

- Add new admin-config utility for persistent configuration management
- Replace hardcoded runtime config with dynamic configuration retrieval
- Enable admin panel to save and apply NocoDB settings immediately
- Add dynamic table ID resolution with fallback to defaults
- Update configuration endpoints to use new persistence system
