Fix resource leaks during config updates

Two follow-up fixes to the dispose cleanup in #13515:

• Only close and recreate the dev-registry dispatcher when its port actually changes, matching the existing runtimeDispatcher behavior. Previously, every config update unconditionally tore down and rebuilt the connection pool, which could cause brief request failures if a registry push was in-flight.
• Dispose old InspectorProxy instances before replacing them during updateConnection(). Previously, stale proxies were silently discarded, leaking their runtime WebSocket connections and 10-second keepalive interval timers.
