Quarantine OpenApiSchemaServiceTests file response schema tests

[github-actions]

Failing Test(s)

• OpenApiSchemaServiceTests.GetOpenApiResponse_HandlesFileContentHttpResultTypeResponse
• OpenApiSchemaServiceTests.GetOpenApiResponse_HandlesFileStreamHttpResultTypeResponse

Error Message

Assert.True() Failure
Expected: True
Actual:   False

The test calls response.Content.TryGetValue("image/png", out var mediaType) (or "application/pdf") and asserts True, meaning the response content dictionary does not contain the expected media type key.

Investigation

Both GetOpenApiResponse_HandlesFileContentHttpResultTypeResponse and GetOpenApiResponse_HandlesFileStreamHttpResultTypeResponse have failed 6 times in the last 30 days (build 1358978).

Failure pattern: response.Content.TryGetValue("image/png") returned false — the OpenAPI response content dictionary does not contain the expected media type entry.

Test context: These tests verify that the OpenAPI schema generation correctly captures file result types (FileContentHttpResult for image/png and FileStreamHttpResult for application/pdf) in the response content schema.

Likely root cause: The OpenApiSchemaService may have a race condition in its schema registration/lookup when processing IFormFile-derived result types. The VerifyOpenApiDocument helper may be checking the schema before all content types are registered.

Alternatively, the TypedResults.File() method's content type metadata may not be consistently available at schema generation time due to lazy initialization or caching behavior.

Recommendation: Examine the OpenAPI document generation pipeline for IResult-based types and specifically how FileContentHttpResult and FileStreamHttpResult media type metadata is registered. Adding explicit media type registration in the route endpoint configuration may resolve the flakiness.
