Perf: cache Nitro client assets and parallelize client page

- Serve /swf and /nitro-assets (~2.8GB) with 7-day Cache-Control plus
  stale-while-revalidate so client opens stop re-fetching hundreds of
  files while asset updates still propagate in the background
- Issue the SSO ticket and the online count query in parallel on the
  client page to shave a round-trip off the critical render path
