feat: background update download, snackbar prompt, chat image rendering

Browse Source 
Update provider: auto-downloads APK in background after finding a newer
version, prompts via snackbar only when ready, cleans up old APKs on
startup. Replaces modal dialog with dismissible snackbar.

Chat bubble: resolve relative image URLs (/api/images/{id}) against
server base URL with auth cookies so search_images results render on
the phone app.
