Fixed playlist loading failure by ensuring the auth token is automatically
restored from localStorage when ApiClient initializes. Previously, the token
was stored but never restored, causing 401 Unauthorized errors on API calls.
Added _restoreTokenFromStorage() method to ApiClient constructor to load
and apply stored token immediately on app startup. This ensures all API
calls (including playlist fetching) have proper authentication.
Fixes: "I still don't have a playlist" issue where playlists were not loading
