Remove hidden cross-service coupling by making dependencies explicit through dependency injection while maintaining backward compatibility via lazy imports. Key changes: - history_service and ban_service: Removed direct module-level imports of fail2ban_metadata_service, added optional service parameters to functions - Added get_fail2ban_metadata_service() provider to dependencies.py - Updated history router to inject Fail2BanMetadataService dependency - history_service functions now use lazy imports in fallback paths for backward compatibility when service is not explicitly injected - All test patches updated to use internal _get_fail2ban_db_path() helper - jail_config_service and jail_service already follow best practices This pattern prevents circular imports, makes services testable via explicit mocking, and documents service dependencies clearly.
