feat: Enhanced error handling with convenience properties and helper methods

This commit significantly improves error handling in the Python SDK by adding:

1. Convenience Properties:
   - Direct access to error code via e.code (instead of e.parsed_exception.code)
   - Direct access to error message via e.error_message
   - Direct access to request ID via e.request_id
   - Direct access to store ID via e.store_id
   - Direct access to authorization model ID via e.authorization_model_id

2. Operation Context:
   - Added operation_name parameter to ApiException and all subclasses
   - Exceptions now track which operation failed (e.g., "Check", "Write")
   - operation_name propagated through api_client call stack

3. Helper Methods:
   - is_validation_error() - Check if error is a validation error
   - is_not_found_error() - Check if error is a not found error
   - is_authentication_error() - Check if error is an authentication error
   - is_authorization_error() - Check if error is an authorization error
   - is_rate_limit_error() - Check if error is a rate limit error
   - is_server_error() - Check if error is a server error
   - is_retryable() - Check if error should be retried

4. Enhanced Error Messages:
   - __str__ method now includes operation name, error code, message,
     request ID, store ID, and authorization model ID
   - More readable and informative error output

5. Testing:
   - Added comprehensive unit tests (17 test cases)
   - Added integration tests against real OpenFGA server
   - Docker Compose setup for integration testing
   - Test documentation and run script

Changes are fully backwards compatible - existing code continues to work.

Files modified:
- openfga_sdk/exceptions.py: Enhanced ApiException and subclasses
- openfga_sdk/api_client.py: Added operation_name parameter propagation
- openfga_sdk/sync/api_client.py: Added operation_name parameter propagation

Files added:
- test/error_handling_improvements_test.py: Unit tests
- test/integration_error_handling_test.py: Integration tests
- docker-compose.integration-test.yml: Test infrastructure
- run_integration_tests.sh: Helper script
- test/README_INTEGRATION_TESTS.md: Test documentation
