/**
 * RdpSession — one tunnel: RdpBridge ↔ WS sender ↔ pixel-office.
 *
 * Mirrors VncSession exactly in structure and message naming conventions:
 *
 *   rdp_ready   — desktop is up; sends { sessionId, name, width, height, colorDepth }
 *   rdp_fbu     — frame-buffer update batch  (same schema as vnc_fbu)
 *   rdp_cursor  — cursor shape change
 *   rdp_close   — session ended (error or intentional)
 *
 * Incoming commands from the browser (via webhookPoller):
 *   fuq         — frame update request (incremental|full; x/y/w/h)
 *   pe          — pointer (mouse) event
 *   ke          — key event
 *   clipboard   — local clipboard pushed to remote
