Fix login race condition when service worker wakes (#308) (#321)

Add ensureOptionsLoaded() to browser action click handler to ensure
login state is loaded from storage before checking isLoggedIn.

This fixes a race condition where clicking the extension icon could
redirect to login even when already authenticated, because the service
worker's in-memory state wasn't restored before the handler executed.
