Sprint 11: Freunde & Chat + Phosphor-Icon-Vollmigration

- Freundschaften (pending/accepted), Nutzersuche, Anfragen per Push
- Direktnachrichten mit Polling, iMessage-Stil, Deep-Links aus Push
- Alle Seiten (map, places, diary, health, dog-profile, sitting, knigge,
  forum, wiki, walks) vollständig auf Phosphor-Icons migriert
- Wikidata-Rassen-Scraper (~833 neue Rassen, lokal gespiegelte Fotos)
- TheDogAPI lokal gespiegelt (169 Rassen + Fotos)
- Quiz-Result-Cards horizontal (korrekte Bildproportionen)
- SW by-v89
