test: RED phase — first test passing for blog.topic model

Setup:
- K8s test job with init container auto-installing itsulu_blog_publisher
- Dockerfile simplified: symlink addon to /var/lib/odoo/addons, no conftest needed
- Postgres init container creates fresh test DB for each job

Fixes:
- Disabled website_blog_publisher_templates.xml (RELAXNG validation issue in Odoo 17)
  Template elements need schema rework; deferred to Phase 2.5
- Fixed XML entity escaping in retained template code (&& → &&)

Test Result:
✅ TestBlogTopicQueueManagement::test_topic_is_created_with_pending_state PASSED
   Model itsulu.blog.topic registers correctly
   Default state='pending' works as expected

Next:
- Run all 7 blog_topic tests to ensure complete coverage
- GREEN phase: implement remaining model methods/fields
- REFACTOR: pre-commit check
