Automatically apply IAntiforgeryMetadata (RequiresValidation=true) for [FromForm] and file upload endpoints. Add [DisableAntiforgery] to opt out and [ValidateAntiforgery] to opt in for non-form endpoints. Add RequireAntiforgeryOnAll() convenience method. Leverages ASP.NET Core's built-in antiforgery middleware with no additional packages. Closes #2407 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The antiforgery PR (#2430) automatically applied IAntiforgeryMetadata to all form endpoints, which caused ASP.NET Core's EndpointMiddleware to throw when UseAntiforgery() was not in the pipeline. This broke all form-related HTTP tests and any standalone test builders. Changed to opt-in via AutoAntiforgeryOnFormEndpoints() on WolverineHttpOptions. Explicit [ValidateAntiforgery] and [DisableAntiforgery] attributes still work regardless of the setting. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
