Hide Control PC in service menu when device is locked

- Adds DeviceLockObserver.isKeyguardLocked using KeyguardManager
- Gates the control_pc main menu item on both the direct-boot user-unlocked state and the keyguard not showing, since UserManager.isUserUnlocked stays true after first unlock
- No refresh wiring needed because the main menu rebuilds its items each time it opens
