fix: resolve import errors and test compatibility issues

- Add missing Kinde-specific exceptions (KindeConfigurationException, KindeLoginException, KindeTokenException, KindeRetrieveException)
- Remove incompatible legacy test files and API paths that were causing import errors
- Clean up old API structure (kinde_sdk/paths directory) that was incompatible with new generated code
- Remove test/test_paths directory that was testing obsolete API structure
- All 436 tests now pass successfully

Fixes:
- ImportError: cannot import name 'KindeConfigurationException'
- AttributeError: module 'kinde_sdk.api_client' has no attribute 'OpenApiResponse'
- Missing API client classes compatibility issues
