fix: watch composite bottom-panel rendered condition incl. focusMode

Address review: bottomPanelVisible alone misses the focusMode case
(splitter hides the panel when focusMode is on, regardless of the
store flag). Compose the same condition the splitter uses so toggling
focusMode while the panel is open also triggers the redraw/resync.
