home: Help, Preview and Logs in one row at the bottom, and What's new tops Settings

Small labelled buttons pinned at the bottom of Home, so cards above can't push them out of sight.
Help and tools leaves Settings, Connection help (the same page as Help) goes, What's new moves to
the top of Settings, the intro replay goes, and the debug build's test message gets its own
section there.
