Remove unused $user variables, add cron container for dev

- Remove 11 unused $user assignments from requireEventOwnership calls
- Add cron container to docker-compose-dev.yml with scheduled tasks:
  expire-pending orders (5min), messenger monitor (hourly),
  meilisearch consistency (daily 3am)
- Cron logs show registered tasks at startup and timestamps per execution
