companion: shown or hidden survives a restart, with a settings switch

SUPER+\ only flipped a property, so every restart of the desktop shell
brought her back. Whether she is shown is now `companion` in Prefs.qml,
set by the IPC and by a switch on a new Settings > Desktop > Companion
page. Prefs gains `ready`, so she waits for the file rather than showing
at the default and then vanishing; the greeting now plays on every
appearance, the one at login included.
