Add missing page filtering/ordering tests (closes #113)

- Add thereIsAPageWithOptions() Behat step supporting reference, createdAt, title, uiComponent, and isTemplate
- Add 7 Behat scenarios in page.feature: order by reference desc, order by createdAt asc/desc, search by reference/title/uiComponent, filter by isTemplate
- Mirrors the filtering coverage already present in layout.feature

All remaining checklist items in #113 were already covered:
- /me username lookup: features/main/security.feature:190
- Page data normalisation (path header, admin bypass, unknown path): features/main/dynamic_page.feature
- OpenAPI factory: features/main/openapi_compatibility.feature + tests/OpenApi/OpenApiFactoryTest.php
