* feat(mcp): advertise the SDK's latest spec revision and validate the RFC 9207 iss
MCPSpecVersion stopped at 2025-06-18 while the pinned SDK negotiates 2025-11-25, and the version LiteLLM puts on its own outbound initialize was a hardcoded historical member. Add the missing revision, name the highest revision we speak once, and pin it to the SDK's LATEST_PROTOCOL_VERSION with a test so the two cannot drift apart silently.
/authorize now seals the issuer it sent the user to into the OAuth state, and /callback holds the authorization response's RFC 9207 iss against it, refusing to forward a code that came back from an authorization server we never sent the user to. An absent iss, an unanchored server row and a state minted before the seal all keep their current behavior.

* fix(mcp): keep params, query and fragment significant in issuer comparison
The shared canonicalizer drops all three, so two issuers differing only outside the path compared equal and a response from another tenant's authorization server would have continued through the flow.
