ControlCenterv2: further steps:

Close drawer before launching activities (feels sloow).
Implement device deletion (untested).
Add app-management icon, remove tap-connected-device-for-primary-activity, hidden (not removed) text hint.
Use level-list for device icon.
Use the new control center when tapping GB notifications.
Added icons to the legacy control center context menu, perhaps it can be embedded in the card?
