fix: update email configuration handling and improve type safety

- Changed the mutation for testing SMTP connection to use an action for better handling.
- Introduced an internal mutation to update the test timestamp for email configurations.
- Enhanced type safety by specifying document types for user and session queries.
- Improved error handling in the SMTP connection test to provide clearer feedback on failures.
