Add isHidden to Category, category CRUD tests, coverage improvements

- Add isHidden field to Category entity with migration (DEFAULT false for existing rows)
- Add isHidden checkbox to edit category template and "Masquee" badge on category list
- Save isHidden in editCategory controller method
- Fix Category.isActive() indentation
- Create CategoryTest with full coverage (14 tests): defaults, setters, setEvent logic, isActive, isHidden
- Add category CRUD tests to AccountControllerTest: add/edit/delete/reorder categories with access control
- Add cookie-consent tests for dev env early return and Cloudflare tunnel script
- Exclude PayoutPdfService from phpunit coverage and SonarQube analysis
