fix: pass ServerCallContext to getAuthenticatedExtendedAgentCard for REST

[ishymko]

Description

Follow-up for #142: authenticated agent card logic relies on context to determine authentication status.

src/server/transports/rest/rest_transport_handler.ts is not exported, so adding a required parameter is fine.

Summary of Changes

Hello @ishymko, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a fix to ensure that the ServerCallContext is correctly passed to the getAuthenticatedExtendedAgentCard logic when handling REST requests. This change is crucial for the authenticated agent card functionality, as it relies on the context to accurately determine the authentication status, addressing a follow-up from previous related issues.

Highlights

• Context Passing: The ServerCallContext is now explicitly passed to the getAuthenticatedExtendedAgentCard function within the REST handler for the /v1/card endpoint.
• Method Signature Update: The getAuthenticatedExtendedAgentCard method in RestTransportHandler has been updated to accept the ServerCallContext as a parameter and forward it to the underlying request handler.

Code Review

This pull request correctly addresses a bug by passing the ServerCallContext to the getAuthenticatedExtendedAgentCard method in the REST transport layer. The changes in rest_handler.ts and rest_transport_handler.ts ensure that authentication context is available for retrieving the agent card, which aligns with the PR's goal. The implementation is straightforward and well-executed. I have reviewed the changes and found no issues.
