feat: Implement node management features including creation, updating, and deletion

- Added CreateNode, UpdateNode, and DeleteNode functions in the controller for managing nodes.
- Introduced NodeInput struct for input validation during node creation and updates.
- Enhanced the Node model to include DiscoveryToken and Pending status.
- Updated the AgentRegister and AgentHeartbeat functions to utilize the new node management logic.
- Refactored the API router to include new routes for node management.
- Improved the frontend Node component to support node creation, editing, and deletion with appropriate UI feedback.
- Added tests to ensure the new functionality works as expected.
