Summary

Dear project team, according to the MCP protocol, we now allow checking for the existence of OAuth defined in a resource before performing OAuth service discovery. The protocol details are here: https://modelcontextprotocol.io/specification/2025-06-18/basic/authorization#sequence-diagram.

This PR implements this check according to the specification. Before performing the default OAuth discovery, it checks for special configuration on the corresponding resource and, if supported by the server, uses custom OAuth support.

This feature is particularly useful for shared MCP server scenarios, allowing users to control OAuth token expiration and callback whitelisting.
