What

bluetoothctl waits forever for bluetoothd. When the service is stopped, or never starts because there is no adapter, get_adapter_powered never returned and the page stayed on "Loading..." indefinitely.

Every bluetoothctl call goes through btctl(), which uses tokio::time::timeout plus kill_on_drop. Limits: 5s for show/devices/info/power/disconnect/remove, 15s for scan, 30s for pair/connect. A timeout returns a readable error.
New get_bluetooth_state checks systemctl is-active bluetooth.service and /sys/class/bluetooth/hci* before calling bluetoothctl. It returns no-adapter, service-off or ready {powered}.
The page now shows a "The Bluetooth service is off" state with a Start Bluetooth button. It runs pkexec systemctl start bluetooth.service (fixed unit, nothing caller-supplied) and then reloads.
Home still uses get_adapter_powered, which is now bounded, so it can't hang either.

Tests

New: a hung command times out and is killed (sleep 30 vs 200ms), quick command output, sysfs adapter detection.
cargo fmt, clippy --all-targets -D warnings, cargo test (147), svelte-check 0/0, npm test, build.
Live BOS VM (no adapter, bluetooth.service inactive): the page shows "No Bluetooth adapter found" immediately. On main it stayed on Loading for 2+ minutes.

Capability changes

Added: the service-off state and the Start Bluetooth button. Nothing removed.

bluetoothctl waits forever for bluetoothd, so with the service stopped (or
no adapter, so it never starts) the Bluetooth page stayed on Loading.
Every bluetoothctl call now goes through btctl(): bounded by a timeout and
killed on drop. get_bluetooth_state checks the service and
/sys/class/bluetooth first and returns no-adapter, service-off or ready.
Service-off shows Start Bluetooth (pkexec systemctl start bluetooth.service,
fixed unit only).

Verified in a BOS VM with no adapter and bluetooth.service inactive: the
page shows No Bluetooth adapter found immediately instead of hanging.
