Quiet the logs and capture the errors that were missing

- Activity page: "Delete all" empties the open tab (api/admin/logs/clear-logs,
  super admin only, logged under system)
- Stop logging every WebSocket connect
- Log unexpected API errors (safeErrorMessage -> logUnexpectedError), every
  failed bot job attempt and every job the queue lost
- Drop the cron jobs' console output; a failed model sync goes to the logs
