Fix/usertokenclient refreshtoken

[rido-min]

fixes #459 and #263

This pull request introduces significant changes to the agents-hosting package, focusing on enhancing token management, improving the CloudAdapter and OAuthFlow classes, and simplifying error handling within the UserTokenClient. The most important updates involve replacing the BaseAdapter with CloudAdapter, improving token refresh logic, and streamlining error handling in the UserTokenClient.

Token Management Enhancements:

• packages/agents-hosting/src/oauth/oAuthFlow.ts: Replaced the initializeTokenClient method with refreshToken, adding token caching and automatic refresh logic using jwt. This ensures that tokens are kept up-to-date and reduces redundant initialization. [1] [2]

Adapter Improvements:

• packages/agents-hosting/src/app/agentApplication.ts: Replaced the BaseAdapter with CloudAdapter and added fallback logic to initialize a new CloudAdapter when no adapter is provided. [1] [2]
• packages/agents-hosting/src/cloudAdapter.ts: Updated the CloudAdapter constructor to support optional parameters for AuthConfiguration, AuthProvider, and UserTokenClient, enabling more flexible initialization.

Error Handling Simplification:

• packages/agents-hosting/src/oauth/userTokenClient.ts: Removed redundant try-catch blocks in methods like getUserToken, signOut, and getSignInResource. Added response interceptors for improved logging and error handling. [1] [2] [3]

Authorization Enhancements:

• packages/agents-hosting/src/app/authorization.ts: Updated the Authorization class to use UserTokenClient for token management, ensuring tighter integration with the new token handling logic. [1] [2]

Miscellaneous Updates:

• packages/agents-hosting/src/oauth/index.ts: Fixed duplicate export of userTokenClient.

Pull Request Overview

This PR enhances token management by introducing automatic refresh and caching in OAuthFlow, streamlines UserTokenClient with Axios interceptors and error handling, and replaces the legacy BaseAdapter with a more flexible CloudAdapter across samples, tests, and application setup.

• Add refreshToken in OAuthFlow using JWT for caching and auto-refresh.
• Refactor UserTokenClient to remove redundant try-catches, add response interceptors, and updateAuthToken.
• Update adapter logic to use CloudAdapter with optional AuthConfiguration, AuthProvider, and UserTokenClient.

• MsalTokenProvider is referenced but not imported. Add import { MsalTokenProvider } from './auth/authProvider' (or the correct path) to avoid runtime errors.
