feat(vnc): echtes Vollbild beim Verbinden (randlos ueber das ganze Display)

Der ⤢-Knopf war nur der Fit/1:1-Umschalter (Zoom) INNERHALB des eingerahmten
Streifens (Header+Dock drumrum) — sah deshalb wie Zoom aus, fuellte nie das
Display. Jetzt oeffnet "Verbinden" die VM in einem Fullscreen-Modal: randlos
ueber alles (Header + Dock weg), scaleViewport passt den VM-Screen sauber ein,
Landscape erlaubt. Buttons schweben drueber (‹ VMs links, ⌨/Strg+Alt+Entf/⤢
rechts, unter der Statusleiste). Android-Back verlaesst Vollbild.

tsc clean. App-only, Deploy: APK.
