fix: drop dead imports from the generated tRPC integration

api.trpc.$.tsx imports createServerFileRoute from
'@tanstack/react-start/server'. The route already uses
`createFileRoute(...)({ server: { handlers } })`, and that symbol is no longer
exported, so the import is both unused (TS6133) and unresolvable (TS2305).

The tRPC branch of root-provider.tsx imports QueryClientProvider but renders
TRPCProvider; setupRouterSsrQueryIntegration is what supplies the query
client.

Generated projects set `noUnusedLocals: true`, so both surface as errors in a
fresh `--add-ons tanstack-query,tRPC` scaffold.

+Drop two dead imports from the generated tRPC integration. `api.trpc.$.tsx`
+imported `createServerFileRoute` from `@tanstack/react-start/server`, but the
+route was already migrated to `createFileRoute(...)({ server: { handlers } })`
+and that symbol is no longer exported, so the leftover import was both unused
+and unresolvable. The tRPC branch of `root-provider.tsx` imported
+`QueryClientProvider`, which it never renders —

+set `noUnusedLocals: true`, so both showed up as errors in a fresh scaffold.
