Restructure project files to follow the addon layout:
- Move models to addons/itsulu_blog_publisher/models/
- Move services (LLM providers, routers) to addons/itsulu_blog_publisher/services/
- Move wizards to addons/itsulu_blog_publisher/wizards/
- Move views (XML templates) to addons/itsulu_blog_publisher/views/
- Move data (cron, mail templates) to addons/itsulu_blog_publisher/data/
- Move security (ACL) to addons/itsulu_blog_publisher/security/
- Move tests and factories to addons/itsulu_blog_publisher/tests/
- Move BDD features to addons/itsulu_blog_publisher/features/
- Create __init__.py files for all Python packages
This enables proper Odoo module discovery and import structure.
