Without _NET_WM_STATE_STICKY the preview overlay only renders on whichever
virtual desktop it opened on — switch desktops mid-dictation and the raw
transcription stream vanishes exactly when you need it (the whole point of
the overlay is that you're working in another app).
visible_on_all_workspaces(true) on the WebviewWindowBuilder sets STICKY via
GTK on X11/XWayland, which KWin + Mutter both honour. Combined with the
existing skip_taskbar(true) — KWin's default Alt+Tab list already respects
_NET_WM_STATE_SKIP_TASKBAR — the preview now behaves like the assistive
overlay it's meant to be: follows you, out of the way of window switchers.
Applied only to the preview window. Task-float and transcript-viewer are
primary surfaces that should stay on their own desktop, so they keep the
current behaviour.
Follow-up if dogfooding shows Alt+Tab clutter on non-KDE compositors: layer
a GTK WindowTypeHint::Utility via with_webview. Not needed for KWin.
Matches OpenWhispr's PR #183 shape for KDE Plasma.
