chore (auth): Enhance token handling and security

Increased rate limit: The default rate limit for API requests has been increased from 10 to 30 requests per minute.

Improved debugging for token caching (which is not working as of this commit).

Error handling in the authentication module has been improved for better logging and debugging.

Refactoring for better readability and maintainability.
