The stream worker discarded ffmpeg stderr, so reconnect loops were opaque.
Capture stderr and log it with the RTSP URL/credentials redacted, so the
real cause (auth, timeout, option, URL parse) is diagnosable without
leaking the source address.

Rewrites internal/ui/window.go in Gio, keeping the Window interface
(NewWindow/Run/Present/PresentAlert/ReportIssue) and the pure-Go ViewModel.
Background updates mutate shared state under a lock and Invalidate; the Gio
loop renders the latest frame. Dual tabs, widget.Image for render's RGBA, a
self-drawn confirm dialog and a MessageBeep sound. Drops lxn/walk (and the
TTM_ADDTOOL/comctl class of problems). Verified via GOOS=windows CGO_ENABLED=0
build of the UI packages; full app build needs Windows+CGo for onnxruntime.
