- Introduced WSSE authentication mode in GrpcAuth component.
- Updated supported authentication modes to include WSSE.
- Refactored gRPC event handlers to streamline authentication header setting.
- Added notes regarding limitations of complex auth modes in gRPC.
* fix: update authentication header retrieval in setAuthHeaders function
- Refactored the setAuthHeaders function to correctly retrieve WSSE and OAuth2 refresh token URLs from the request object instead of the collectionAuth object.
- Added comprehensive tests for various authentication modes, ensuring proper inheritance and request-level overrides for AWS v4, basic, bearer, digest, NTLM, WSSE, API key, and OAuth2 authentication methods.
