Add .qmlformat.ini, qmlls support, and format QML files

- Enable QT_QML_GENERATE_QMLLS_INI for QML Language Server support
- Add IMPORT_PATH to demo's qt_add_qml_module so .qmlls.ini includes
  the local build QML directory alongside the Qt system path
- Add editor setup section to README with qmlls and qmlformat guidance
- Add QML formatting section to French guide
- Reformat demo QML files with .qmlformat.ini (line wrapping at 80 cols)
