fix: User-facing Strings Cards → Cardecky komplett, Build 3
User-facing Rebrand:
- LoginView Heading (war schon in v0.8.5)
- NotificationManager.title (war schon in v0.8.5)
- ShareEditorView Footer-Text: "...in der Cards-App" → "...in der Cardecky-App"
- StudyAppIntents Description: "Öffnet Cards" → "Öffnet Cardecky"
- Localizable.xcstrings: "Cards" key → "Cardecky"
- NSPhotoLibraryUsageDescription: "Cards greift..." → "Cardecky greift..."
- Log.app.info("Cards starting") → "Cardecky starting"
- MARKETING_COPY.md: alle "Cards"-Treffer in DE + EN auf Cardecky
- RELEASE_CHECKLIST: App-Name "Cards" → "Cardecky"
Build-Nummer 2 → 3 (Apple lehnt doppelte Build-Nummern ab, Code-
Hash hat sich geändert).
Code-Identifier bleiben: CardsAPI, CardsTheme, CardsNativeApp,
CardsWidgetExtension, CardsShareExtension — interne Symbol-Namen,
nicht user-facing.
Archive verifiziert: CFBundleDisplayName=Cardecky, Build=3.
