Roland 2328524ab2 controller: VNC toggle, gated on the Desktop running
Add a VNC toggle to the Controller (both UIs) that starts/stops whichever VNC
backend is installed: wayvnc for Wayland (Raspberry Pi OS), RealVNC for X11.

Runtime-only, like the Desktop toggle: the unit is never enabled, so VNC does
not return after a reboot. Users who want it permanently on can enable it with
raspi-config.

VNC serves the desktop session, so starting it without a desktop gives clients
a blank screen. The gate lives in the backend, not just the UI, so curl callers
get it too (409, distinct from a systemctl failure). Stopping is never gated so
a running VNC server can't be stranded on with no way to turn it off.

Backend selection deliberately avoids raspi-config's live-compositor probe
(pgrep labwc), which reports X11 — and would pick the wrong backend — whenever
the desktop is stopped. wayvnc also requires its config to exist; that is
checked directly rather than via the unit's ConditionResult, which reports 'no'
for any unit that has never been started.

Extracts _unit_properties()/_systemctl_unit() so Desktop and VNC share one
systemd probe and start/stop path.
