A far-right status-bar control shows the current theme and opens an
anchored popover (not the full-screen modal) to switch live: click or
keyboard (arrow/Enter to pick, Esc/tap-away to dismiss without change).
Reuses ThemeController.available/select; the theme.pick palette command
is unchanged (D-6 parity). Registered at priority 110 so it sits in the
status bar's right group.
Closes T-234 (under no parent; demo polish).
