- Add FastAPI application with lifespan management
- Implement bearer token authentication (read/admin levels)
- Create comprehensive REST API routes:
- Nodes: list, get by public key
- Node tags: CRUD operations
- Messages: list with filters, get by ID
- Advertisements: list with filters, get by ID
- Telemetry: list with filters, get by ID
- Trace paths: list with filters, get by ID
- Commands: send message, channel message, advertisement
- Dashboard: stats API and HTML dashboard
- Add API CLI command for running the server
- Create API test suite with 44 passing tests
Routes use proper RESTful status codes (201 Created, 204 No Content).
Authentication is optional - when keys not configured, endpoints are open.
