d-q/odoo_addons — reverse-engineered prompt

I want you to turn this into a working Odoo addon, probably centered around the existing owl self service module. The goal is a simple self service experience inside Odoo with a clean modern interface, so a normal user can open it and handle their own basic actions without needing admin help.

Please flesh out whatever is missing so it installs cleanly, works end to end, and feels polished in the browser. Use the existing project structure as the source of truth, and keep the feature scope realistic to what is already here. If something is unclear, make sensible Odoo style choices instead of overengineering it.

I also want the module to look decent out of the box, with responsive styling and straightforward screens, and include any needed menus, views, access rules, demo or sample data, and setup notes so someone can actually try it quickly.

If you need to, look up current Odoo docs online, but keep the result practical and ready to run.
