feat(waybar): island floating 3-pills + popups + deploy

- Config waybar 3-pills glassmorphism (left/center/right)
- Scripts : gpu, network, power-profile (toggle+luminosité/profil),
  cava daemon+reader, wob (volume/luminosité), rofi-launcher
- Popup media GTK3 : volume sortie+entrée + luminosité (vc-media-popup.py)
- Profil énergie : cycle balanced→low-power→performance avec brightnessctl
- Autostart COSMIC : waybar.desktop + wob.desktop
- Thème COSMIC Light ajouté (accent violet-chaton)
- deploy : +autostart, +sudoers platform_profile, +udev platform_profile,
  +scripts .py waybar, +CosmicTheme.Light
