perf(playground): cache MCP UI resource fetch via React Query
Each `<McpAppView>` mount opens a fresh raw MCP client in the main
process to call `fetchUiResource`. With virtualized chat threads
(see PR #2192) historical rows unmount and remount whenever they
leave/re-enter the viewport, which would trigger a reconnect storm
on threads with multiple MCP UI cards.
Wraps the IPC call in `useQuery` keyed by [serverName, resourceUri]
with `staleTime: Infinity` / `gcTime: Infinity` and `retry: false`,
so a remount paints from cache immediately and no IPC fires until
the resource URI actually changes.
Addresses Copilot review on #2192.
