refactor(island): the controls panel goes

Each of its seven tiles opened a drawer page that already existed, and it
went unused. SUPER alone will open the drawer instead. Removed with it: the
status pill's controls icon, Island.toggleControls, the island IPC target,
Controls.js and its test, and the controls list in Prefs. Prefs now holds
only the pinned IP; a controls key left in desktop.json is still kept on
write, because writes merge into the parsed document.
