feat(yoga14): remote control, app management, install script

- Add keycode module: G7BTS Rii remote control support (evdev, auto-reconnect)
- Add key bindings: single/double press detection with configurable window
  - KEY_HOMEPAGE: single=VacuumTube, double=LiveboxTV
  - KEY_OK: inject Enter keypress via ydotool
  - KEY_PAGEUP/DOWN: LiveboxTV channel navigation
- Add M3U parser and channel selector for LiveboxTV (51 channels)
- Add volume entity (wpctl/PipeWire, 2s polling)
- Add app management: vacuum_tube, livebox_tv (start/stop/state via MQTT)
- Add grace period to prevent app state bounce after stop
- Fix screen ON via GNOME busctl: add SimulateUserActivity
- Fix power commands: trigger on ON, publish OFF immediately (momentary buttons)
- Disable GPU temp/usage entities
- Add install script: build, deploy to ~/pilot, systemd user service
- Fix service startup: WantedBy=graphical-session.target (full GNOME env at launch)
