event: make startup behavior multi-worker-safe

Assorted:
  - Relative symlinks for event assets/templates were already
    committed and are safe to make permanent anyway. Get rid of the
    code to tear down and relink them. Too many moving parts, though
    a valiant effort.
  - Build Event table directly from DB engine to avoid app context
    shenanigans.
  - Don't let chat workers build the table. Makes local testing much
    clearer.
  - Fix localhost not loading remote chat_done.js.
