Enhance OAuth2TokenManager with improved error handling and constants
- Added new error messages for loading and clearing OAuth2 tokens in `constants.ts`. - Updated `OAuth2TokenManager` to throw specific errors when loading and clearing tokens fails. - Refactored tests to ensure comprehensive coverage of token validation scenarios, including handling of empty, null, and expired tokens. These changes improve the robustness and clarity of the OAuth2 token management implementation, enhancing error handling and overall code quality.
