Add dedicated signature permissions to platform manifest and shell manifest which could enable/disable BT and Wifi state on watch

Skip Bluetooth consent UI if running on shell, also fix a typo in log message.

Test: Manual test running `adb root; adb shell service call bluetooth_manager 6` and see if BT is on without consent UI.
