zhanghongyu_0626 6d780d45c3 feat(auth): Enhance JWT handling and error management in authentication flow
- Updated the login endpoint to utilize shared JWT issuer/audience settings, improving consistency across modules.
- Introduced error handling for unknown accounts during token issuance, raising an UnauthorizedError when necessary.
- Enhanced traceability by adding trace and request IDs to responses, ensuring better tracking of requests.
- Refactored exception handling in middleware to properly bubble up application-specific errors, preventing them from being swallowed.
- Added new utility functions for generating trace headers to improve debugging capabilities.

This update strengthens the authentication process and enhances error visibility, contributing to a more robust and maintainable codebase.
