Clicking the keyboard glyph now opens a KeyboardPanel popup (the native
bar pattern, e.g. omarchy.audio) instead of toggling pause directly:
Show keys toggle, Mode (all | bindings), and Position (bottom/top/
center). The toggle writes the pause flag and the options write
config.json, both watched by the display panel, so menu and overlay
stay in sync across monitors. Replaces BarWidget.qml with a Panel-based
widget (Panel + BarIconButton + KeyboardPanel).
