fix(endorserServer): improve type safety and error handling

- Update claimSummary to handle both GenericVerifiableCredential and GenericCredWrapper types
- Fix logger error handling in register function to properly stringify response data
- Add type narrowing with 'claim' in claim check for safer type handling
- Improve error message formatting for registration errors

This change improves type safety by properly handling different claim types
and ensures consistent error logging. The registration error handling now
properly stringifies response data for better debugging.
