Fetched actor record to display real name when listing audit log events

no issue

- switched `parse-audit-log-event` to a class helper to get access to dependency injection
- added `get actor()` to the parsed event object
  - uses the store to find the related user record, returning an already loaded record if it exists otherwise fetches the record
  - allows use of `event.actor.*` in templates because they are promise-aware and will be filled in once the record is loaded
