Feature: Hundepass — Ausweis integriert, Icons & Kontrast-Fix

- Ausweis-Button aus Profil-Ansicht entfernt; stattdessen "Ausweis öffnen"-Button im Hundepass-Modal-Footer
- Bearbeiten-Button in Gesundheits-Info von btn-link auf btn-secondary (besserer Kontrast)
- 7 fehlende Phosphor-Icons zum Sprite hinzugefügt: file-pdf, notebook, link, identification-card, wave-sine, list-checks, share-network
- Leere Sektionen (Impfungen, Medikamente) zeigen einladenden Empty-State mit Icon statt nacktem Text
