feat: add node HTTP control, engine-to-node communication, connect-input/output API

- Node control server now accepts HTTP POST /cmd for command dispatch
  (in addition to existing WebSocket control)
- Added NodeControlClient: engine sends commands to nodes via HTTP POST
- New REST endpoints:
  POST /api/graph/nodes/:id/connect-input  - connect node input to MXL flow
  POST /api/graph/nodes/:id/connect-output - create new MXL flow + connect output
  POST /api/graph/nodes/:id/disconnect-port - remove reader/writer
  POST /api/graph/nodes/:id/command - send raw command to node
- Flow IDs now use proper UUID v4 format (MXL requires standard UUIDs)
- Flow definitions use NMOS format (urn:x-nmos:format:video)
- Engine passes --mxl-domain to node processes
- User-provided node IDs (via 'id' field in POST body)
- End-to-end verified: testsrc → passthrough → new MXL output flow
