fix: skip proxy update checker in Electron mode (#89)

Electron has its own native auto-updater (electron-updater) that handles
download and install via system tray. The backend's startProxyUpdateChecker()
was also running, causing the web UI UpdateModal to pop up and conflict
with the native updater.

- Skip startProxyUpdateChecker() when deploy mode is "electron"
- Don't auto-open UpdateModal in Electron mode
