Problem Details support

Support for RFC-compliant Problem Details has been added to elmah.io. When your API returns a ProblemDetails response, elmah.io now automatically detects it, parses the standard fields, and shows them in a structured format instead of raw JSON. Validation errors from ASP.NET Core are shown in a dedicated errors table, making it easy to see which fields failed and why. This makes debugging API-level issues significantly faster, especially when working with model validation or custom ProblemDetails implementations. No configuration changes are required, and existing logs will automatically benefit from the improved visualization.
