fix: preserve node_modules during upgrade to avoid re-downloading Electron

Browse Source 
The upgrade was wiping node_modules then relying on npm to re-download the
~120MB Electron binary. npm returns exit 0 even when the download times out,
leaving the kiosk with no Electron binary and a blank screen on next boot.

node_modules only needs to be deleted on a fresh install or when explicitly
changing Electron version. For a JS-file-only upgrade, npm install without
a wipe is either a no-op (no changes) or applies dependency updates cleanly.
The install_electron_binary fallback remains as a safety net.
