fix(state): gate list fetches on server capability (#1350) (#1395)
The four list-fetching state managers fired their list RPC against every
server on connect regardless of advertised capabilities, so a server that
doesn't implement a given primitive replied -32601 "Method not found",
surfacing in the console on every connect. Mirrors the `tasks`-capability
gate added for ManagedRequestorTasksState in #1349.

- managedToolsState        → gate on capabilities.tools
- managedPromptsState      → gate on capabilities.prompts
- managedResourcesState    → gate on capabilities.resources
- managedResourceTemplatesState → gate on capabilities.resources
  (the spec defines no separate resourceTemplates capability;
  resources/templates/list is part of the resources surface)

When the capability is absent each manager sets an empty list, dispatches
its change event, and returns — the right semantics for "this server
doesn't support X."

Tests: existing flow tests now construct their FakeInspectorClient with
the relevant capability so the live list path is still exercised; added a
"refresh skips listX when capability absent" and a "connect against an
X-less server doesn't fire listX" test per manager. Updated the
useManagedX peers and resourceSubscriptionsState (which drives a
ManagedResourcesState refresh) to advertise the capability too.
