F ix work access token (#810)

* feat: enhance WorkAccessToken to include AgentID for improved token management

- Added AgentID field to WorkAccessToken struct.
- Updated NewWorkAccessToken function to accept AgentID as a parameter.
- Modified access token cache key to incorporate AgentID, ensuring unique cache entries per agent.

This change improves the handling of access tokens in a multi-agent environment.

* refactor: enhance WorkAccessToken to improve cache key handling

- Updated the AgentID field in WorkAccessToken struct to clarify its optional nature for distinguishing applications.
- Modified the access token cache key construction to support both new and legacy formats based on the presence of AgentID.
- Added comments for better understanding of the cache key logic and its compatibility with historical versions.

This change improves the flexibility and clarity of access token management in multi-agent scenarios.

* feat: enhance WorkAccessToken with new constructor for AgentID support

- Introduced NewWorkAccessTokenWithAgentID function to maintain backward compatibility while allowing for AgentID usage.
- Updated NewWorkAccessToken to call the new constructor, ensuring seamless integration.
- Improved error handling in GetAccessTokenContext by checking for cache availability and handling potential errors during cache operations.

This change enhances the flexibility of access token management, particularly in multi-agent scenarios, while ensuring compatibility with existing implementations.
