perf: static file fast path + remove info() log on every request

- Add fast path in processorResource._handle() for static assets (.js/.css/.png/.jpg/.gif/.ico/.svg/.woff etc)
  Static files skip auth closures, i18n, url2processor, isHtml overhead
- Remove info() call in checkAuth() middleware that logged on EVERY request
  (was causing disk flush on every request, blocking the async event loop)
- Log output now only uses debug() for timecost, exception() for errors
