Fix critical bugs in app_urls

- init_db.py: parameterize SQL queries to prevent SQL injection
- scheduled_tasks.json: resolve duplicate periodic task pk (4 -> 15)
- db_utils.py: use function parameter in _get_status_pattern_matching
  instead of capturing the enclosing scope variable
- url_detail.html: fix wrong field name image_urls -> images_url
- settings.py: align Celery queues (default/light/heavy) with the task
  queues and supervisord workers
- Add /task/publish_<id>/ route to fix broken publish links in templates
