Recording popup, level meters, UX polish

- Recording tray icon opens popup (mics + active recording streams)
- Recording stream level meters forward from parent source signal
- RecordingTray subclass for single-click (no double-click needed)
- Context menu Set Default Output/Input shows checkmark when active
- Last DeviceWidget in each row hides its right separator
- Popup horizontal layout, configurable content (output/mic/apps)
- Single-click tray, right-click menu for Open Mixer
- Desktop file, icon, CMake install rules
- Window bring-to-front across workspaces (KWin::forceActiveWindow)
