Relay a GET to the board's GenAI Studio backend
GET/api/genai/:subpath
Forwards the request, with its query string, to the configured board and streams the response back unchanged: status, body, content type and the Studio's X-* headers. Server-sent event streams such as models/logs/stream pass through unbuffered, and binary answers such as the JPEG from board-camera/snapshot?device=/dev/videoN byte for byte. The board's self-signed certificate is accepted for the configured address only.
