fix(endorserServer): improve type safety in claim handling

- Fix type conversion in claimSpecialDescription to properly handle GenericVerifiableCredential
- Update claim type checking to use 'claim' in claim for proper type narrowing
- Add type assertions for claim.object to ensure type safety
- Remove incorrect GenericCredWrapper type cast

This change resolves the type conversion error by properly handling
different claim types and ensuring type safety when passing objects
to claimSummary. The code now correctly distinguishes between
GenericVerifiableCredential and GenericCredWrapper types.
