The Hotspot, Bluetooth, Desktop, VNC and Throttle toggles had each been written
out longhand at four layers. Collapse the shared parts:
- useSubsystemToggle() replaces five near-identical hooks. This also fixes a
latent bug: only useDesktop/useVnc restored state when a request failed, so a
failed Bluetooth/Throttle/Hotspot toggle left at null and — since the
status poll sees no change — the toggle stayed disabled and read as
unsupported until it remounted.
- SubsystemToggle renders all five, with the Desktop's stop confirmation and
VNC's desktop gating as declared options rather than bespoke copies.
- The fallback UI's four update*/toggle* pairs become one config-driven
implementation (-100 lines).
- _raise_for_action() centralises the 13 endpoint failure checks, including
VNC's 409-vs-500 split.
Deliberately not shared: the six get_*_status_dict() builders (payloads
genuinely differ) and the per-subsystem mechanisms (nmcli/rfkill/sysfs/systemctl).

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.

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.

* POST /api/hotspot/settings checks is_docker_mode() directly instead of
string-matching the error message (still 500, matching the sibling
hotspot/bluetooth/throttle endpoints).
* Escape \ ; , " in the WiFi QR code per the WPA QR format.
* Skip the controller.yaml write when a settings update changes nothing.

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.
