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.
