Create a remote control (VNC) session for a node and return a short-lived token for WebSocket connection. This is a convenience endpoint that automatically determines VNC connection parameters based on the node's configuration.

The endpoint uses the node's configured VNC port and proxy settings to establish a TCP tunnel. The returned token should be used to connect to the WebSocket endpoint /v1/tcp-proxy/{token}.

Two-Phase Authorization Flow:

1. Call this endpoint with Bearer token authentication
2. Server establishes VNC tunnel via agent and returns a session token
3. Connect to /v1/tcp-proxy/{token} WebSocket endpoint (no auth header needed)

Required Permissions:

• System access right: SYSTEM_ACCESS_SETUP_TCP_PROXY
• Object access rights: OBJECT_ACCESS_READ and OBJECT_ACCESS_CONTROL on the node
