Lead Home with what's happening, and give settings a page

Home answers "what's my headset doing, and what do I want to do now". A
Right now card says whether SteamVR is running and holds the volume and the
next things people do: cast to this screen, play a video or photo, show a
Mac window, send files, type on the Frame. With nothing captured, the
headset view is a short strip rather than a big black box; the keyboard and
trackpad fold to one line until turned on; VR performance folds away.
Screenshots and Family and comfort follow.

Tools is grouped: in the headset (Mac in the headset, the media player, the
panel switcher), then sending files, Linux apps, remote and power. Privacy
and updates, library artwork and the assistant move to a Settings page,
opened by a gear in the header (key 6), with About and licences.

Family and comfort no longer fills the form with a finished session's
settings, so it shows 30 / 20 / 30 rather than the last test's 1 / 0 / 0,
and its recent events carry their times.
