Greptile P1 (security): with both stacks installed, selection keyed only off
wayvnc's unit and config. If RealVNC was the one running, status reported VNC
as off and stop targeted wayvnc — leaving the screen remotely accessible while
the UI claimed VNC was off. Reproduced on 10.0.0.8: RealVNC serving on 5900
reported as running=false.
Now every installed backend is reported with its own active state: status is on
when any backend runs and names the one actually serving, and stop stops all
running backends. wayvnc is still preferred for starting.
Greptile P2 (latency): both units are probed in a single multi-unit
`systemctl show`, and the status dict no longer re-probes, so VNC adds one
subprocess to /api/stats rather than three.

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.

Stopping the display manager left the Pi's monitor black with only a blinking
cursor. The console VT is already in the foreground with a getty and a live
shell on it (verified: /dev/vcs1 holds the login banner and prompt) — the
display manager just hands the display back without the console being
repainted, so nothing is visible.
Activate the console VT, then bounce off another VT to force a modeset and
redraw, and print a short message telling the user the Controller stopped the
desktop and how to start it again.
Best-effort throughout: skipped when no getty is on the console VT, a chvt or
console-write failure never fails the stop, and being stranded on the repaint
VT is reported rather than claimed as success. Verified on 10.0.0.8 hardware.

Add a Desktop toggle to the Controller (both UIs) that starts/stops
display-manager.service. Fail open: the unit is never enabled/disabled,
so the desktop always returns on reboot; users who want it disabled
across reboots can set the default target themselves.
Rename the hotspot and bluetooth actions to reflect their real behavior:
- enable/disable_hotspot -> start/stop_hotspot (/api/hotspot/start|stop)
- enable/disable_bluetooth -> unblock/block_bluetooth (rfkill semantics,
/api/bluetooth/unblock|block)

Probe the selected WiFi device with iw to determine which hotspot
protocols it can host: WPA2 requires AP mode; WPA3 requires SAE in AP
mode (SAE_OFFLOAD_AP, or a mac80211 driver with the CMAC cipher for
software SAE). The Raspberry Pi's brcmfmac supports neither, so Pis
correctly offer WPA2 only (verified against real Pi 4/Pi 5 iw output).
The protocol is saved as hotspot.protocol in controller.yaml.
enable_hotspot() now always sets the Hotspot connection's key-mgmt
explicitly (sae + required PMF for WPA3) so a reused profile cannot
keep a stale protocol, and reverts to WPA2 if the driver rejects SAE.
New GET /api/hotspot/protocols endpoint; protocol dropdowns added to
both the ControllerPage React UI and the fallback controller UI.

Hotspot was reported as "not supported" on x86 machines (Ubuntu/Debian PCs)
because the Controller only watched the hardcoded default wlan0 device, while
predictable interface naming produces names like wlp2s0. The Settings page
saved hotspot_device to wrolpi.yaml, which the Controller never read.
The Controller now owns hotspot settings in controller.yaml:
* New endpoints: GET/POST /api/hotspot/settings, GET /api/hotspot/devices
(WiFi interfaces discovered via nmcli).
* Legacy hotspot_* values in wrolpi.yaml are migrated into controller.yaml
once on startup, unless controller.yaml already sets them.
* The Hotspot SSID/password/device fields moved from the Settings page to the
Control page next to the Hotspot toggle; the device is now a dropdown of
the WiFi devices found on the machine.
* The Controller fallback UI gets the same hotspot settings form for parity.
