companion: remove from the tree, archived as tag archive/companion

The chibi 2B companion is retired for now. Its last state is kept in the
signed tag archive/companion (the commit before this one), so it can be
revisited with `git checkout archive/companion`; hypr-theme carries a tag
of the same name for its compositor hooks (typing/delete events and the
SUPER+\ bind).

Removed with it, since nothing else used them: the Companion, phrases
and artists settings pages, the five companion prefs in Prefs.qml and
Prefs.ready, the wallpaper heart (Admired.qml's list), the assistant's
replied() signal and cardTop, and the keybinds reminder's name for the
code:49 bind. The design specs and plans under docs/ stay as history.
