Closes: #2430 OpenAPI 3.1 allows a schema whose only type is "null", which validates exactly the JSON value null. The type dispatch in oapiSchemaToGoType had no branch for it, so codegen failed with "unhandled Schema type: &[null]". Map such schemas to `any`, mirroring the permissive mapping used for typeless schemas, and skip the optional pointer since nil is already the zero value of `any`. Includes a regression test under internal/test/issues/issue-2430. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
