refactor(hypercert): restructure hypercert resolver and related components

Refactored hypercert-related code to improve organization and maintainability:
- Moved HypercertResolver from graphql to services directory
- Updated import paths in composed resolver
- Enhanced HypercertsEntityService with comprehensive documentation
- Added detailed JSDoc comments for HypercertService and ClaimsQueryStrategy
- Introduced comprehensive test coverage for HypercertsService, ClaimsQueryStrategy, and HypercertResolver
- Improved error handling to return null for failed resolver queries
- Updated schema to add new fields and improve type safety
