Enhance authentication and logging configurations

- Updated `AuthController` to monitor backdoor parameters and enhance user credential validation.
- Changed route for `Hash` method in `CryptController` for clarity.
- Improved case-insensitivity in username comparisons in `BackdoorExtensions`.
- Modified logging setup in `Program.cs` to clear providers and set minimum level to Trace.
- Added separate logging configuration for warnings in `appsettings.json`.
- Restructured `backdoors.json` to encapsulate entries within `BackdoorParams`.
