Sprint 6: Karte / Orte / Routen mit GPS-Aufzeichnung

- backend/routes/places.py: CRUD für hundefreundliche Orte (6 Typen)
- backend/routes/routen.py: CRUD für Gassi-Routen mit GPS-Track (JSON)
- main.py: beide Router eingehängt (/api/places, /api/routes)
- api.js: places + routes erweitert (list, update, delete)
- pages/places.js: Karte + Liste, Typ-Filter, Ort anlegen/bearbeiten
- pages/routes.js: Routen entdecken + GPS-Aufzeichnung mit Stoppuhr
- pages/map.js: zentrale Übersichtskarte (Orte + Giftköder, Layer-Toggle)
- components.css: Styles für alle drei neuen Seiten
- sw.js: by-v19 → by-v20
