full-day workshop: Include the page data owner in the filter exercise

Problem

Step 6 says filtering requires the Flask backend, tests, and Astro frontend, but tells learners to supply only:

• app/server/app.py
• app/server/test_app.py
• app/client/src/components/DogList.astro

app/client/src/pages/index.astro owns the /api/dogs request, reads URL query parameters, and renders pagination. DogList.astro only renders the dogs prop. Omitting the page owner encourages a partial implementation that cannot reliably connect controls to server-side query parameters or preserve pagination behavior.

Suggested change

Include index.astro in the prescribed context and add implementation-agnostic behavior checks.

Acceptance criteria

• Step 6 includes app/client/src/pages/index.astro in Copilot context.
• The prompt requirements describe how control changes reach the API.
• Breed-only, availability-only, and combined filtering are validated.
• Clearing filters restores the full list.
• Filter changes handle the current page deliberately, such as resetting to page 1.
• Updated unit tests prove endpoint filtering rather than only the original response shape.

Beginne mit den Workshop-Anweisungen zu Step 6 und untersuche app/server/app.py, app/server/test_app.py, app/client/src/pages/index.astro und app/client/src/components/DogList.astro. Aktualisiere die vorgegebenen Anforderungen an Kontext und Verhalten, sodass das API-verbundene Filtern, Leeren und die Seitenverwaltung ausdrücklich festgelegt sind, und führe anschließend die aktualisierten Unit-Tests aus, um die Endpunktfilterung für die Fälle nur nach Rasse, nur nach Verfügbarkeit und kombiniert zu überprüfen.
