Fix AuthPanel serialization issue with PDO objects

The identity object and authentication providers contained references
to PDO connections which cannot be serialized. This caused DebugKit
to fail when viewing the Auth panel.

Changes:
- Store identity->getOriginalData() instead of the raw Identity object
- Store provider class names as strings instead of provider objects
- Update template to work with the new data structure
