Split the bar panel into one QML file per stage

Panel.qml keeps the state, the CLI calls and the stage switch (889 lines,
was 2360); each stage is its own file taking the panel as a required
property. The omarchy installer copies every QML/JS file and clears stale
ones. tests/static.sh filters qmllint on [syntax], not the word error.
