style: fix lint for the banner/adaptive changes

- ruff format and import ordering (main_window, data_collection_settings,
  beam_center_panel, beamline_state_panel)
- rename unused unpacked variable in test_title_label
- replace the mousePressEvent monkeypatch on the beamline state title
  with a proper eventFilter so basedpyright accepts the diff
