Fix settings/plugin window bugs; remove example plugin

- Add missing QGroupBox import to settings_window (caused silent crash on open)
- Remove Controls tab and _controls_tab() method from settings
- Clamp child window positions to screen bounds so they don't go off-screen on Windows when main window is maximized
- Apply same screen-clamp fix to Motion Capture plugin window
- Delete example plugin; disable it in enabled.json
