OAuth protected-resource metadata for the ChatGPT MCP surface

Returns the RFC 9728 path-scoped protected-resource metadata for the /mcp/chatgpt MCP surface, which is what its WWW-Authenticate challenge names on a 401. Identical to the origin-wide document except that resource names /mcp/chatgpt on this origin rather than the origin itself, so a client can check the document answers for the endpoint it called.
