feat: Phase 4 complete — RDP via ironrdp

Rust RDP service: ironrdp client with full connection handshake
(TCP -> TLS -> CredSSP -> NLA), pixel buffer frame delivery,
mouse/keyboard input via scancode mapping, graceful disconnect.
Runs in dedicated thread with own tokio runtime to avoid Send
lifetime issues with ironrdp trait objects.

Vue frontend: RdpView canvas renderer with 30fps polling,
mouse/keyboard capture, RdpToolbar with Ctrl+Alt+Del and
clipboard. SessionContainer handles both SSH and RDP tabs.
