Tin 05f39bf942 fix(mcp): invalidate a browser-authorized upstream token when a mint-relevant field changes
An admin who ran Authorize & Fetch and then changed a field that determines which upstream OAuth
token gets minted kept using the stale token for tool preview, sessionStorage, and (on the backend)
the stored per-user credential and its cache. Grounded in RFC 8707/8693 and the MCP auth spec, a token
is bound to one tuple: resource/audience (url), OAuth mode/grant (auth_type, oauth_flow_type), the
authorization-server endpoints, and the OAuth client + scopes. A shared getOAuthAuthorizationIdentity
captures exactly those fields; transport (http/sse on the same url is the same audience) and
delegate_auth_to_upstream (a downstream-usage toggle never sent to the authorize request) are excluded.

UI: both the create and edit forms now discard the held token (React state / sessionStorage / hook,
plus the fetched token + DCR client in form.credentials) whenever the identity diverges from the one it
was authorized against, re-applying the admin's in-flight edit so it is never wiped. The check lives in
one shared helper so the two forms cannot drift.

Backend: editing an MCP server now compares the pre/post identity and, on a mint-relevant change, purges
every stored per-user OAuth credential for the server (DB row + per-user token cache) so no user
forwards a token minted for a resource/AS/client that no longer matches. Best-effort; a purge failure
never fails the update.
