Electron CI Build + Version Info Modal

CI Pipeline:
- New electron-build stage (electronuserland/builder:wine) builds Windows installer
- New electron-deploy stage copies artifacts to container /data/downloads/
- Triggers on electron/ or VERSION changes + manual trigger
- bump-version now syncs electron/package.json via jq

Version Modal:
- Click version badge to open info modal
- Shows Hub Version, Desktop App Version, Server status
- Hint when versions differ (update available)
- Download link when not using Electron app
- Escape + overlay click to close
