feat(surf): serve startup summary, shutdown report and http request log

- serve prints a startup summary on a terminal (version, environment, URL,
  admin, database host and name, pending migrations, plugins, drivers) and
  logs it as a 'startup summary' record plus 'listening on <addr>'
- on SIGINT/SIGTERM serve drains, prints and logs a shutdown report and
  returns nil (exit 0), or the drain errors (exit 1)
- the request log is on by default under diary component http with
  request_id; the route pattern, never the path, is logged
- lagoon.PendingMigrations, conga.Worker.Stats, diary.HideOnTTY,
  bonfire.IsTerminal and bonfire.Details back the summary and report
