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.
Replaced the `Logging` configuration in both `appsettings.json`
and `appsettings.Development.json` with Serilog, enabling
structured logging with configurable sinks and enrichment.
Added `DocumentOperatorSettings` to manage temporary files
and logging details. Introduced `RedisSettings` for Redis
integration, including connection string and cache settings.
Added `ApiKeySettings` to support tenant-specific API key
validation with detailed configuration for each tenant.
These changes improve logging, caching, and configuration
management for better maintainability and extensibility.
