fix(mcp): stop proxy-started legacy listeners from consuming server rpm (#46968) 
* fix(mcp): stop proxy-started legacy listeners from consuming server rpm

The listener the proxy opens on notifications/initialized for legacy MCP
sessions ran the server rate-limit admission once per target, so every
session spent an rpm slot before the client sent anything. Admission is
now injected into the listener and applied only to client-initiated
subscriptions (subscriptions/listen and resources/subscribe). Authorization
and its periodic recheck still run on every path.

* test(mcp): key the fake admission window by caller and server

* fix(mcp): stop subscription catalog refreshes from consuming server rpm

A subscription listener lists the caller's catalog to diff list_changed
events, at setup and on every upstream event. Those listings went through
the normal per-server admission, so against an upstream that declares
listChanged each legacy session spent several rpm slots before the client
asked for anything. The listener now marks its targets as already admitted
for its own lifetime, so its refreshes reuse the subscription's admission.
Client requests on the session are still metered.

* test(mcp): exercise subscription admission through the proxy rate limiter
