This commit implements a complete rebranding of the project: - Updated all namespaces from `DocumentOperator` to `DocumentService`. - Renamed file paths, embedded resources, and test data references. - Updated configuration keys, logging paths, and Redis instance names. - Revised documentation to reflect the new project name. - Modified project and solution files to align with the new structure. - Updated class names, DTOs, commands, queries, and handlers. - Adjusted middleware, controllers, and API endpoints. - Updated Swagger metadata and API titles to `DocumentService API`. - Refactored test namespaces, resource paths, and embedded resources. - Updated build and deployment configurations for the new name. - Replaced all references to `DocumentOperator` in comments and literals. These changes ensure consistency across the codebase and documentation.
