iOS Capacitor build

[satsdisco]

Summary

Android app exists and works via Capacitor. iOS is listed as "ready to add" but not yet built. For Samizdat to be a true freedom press tool, it needs to be on both platforms.

Tasks

• Add iOS platform (npx cap add ios)
• Configure signing and provisioning
• Handle iOS-specific safe areas (notch, home indicator)
• Test NIP-46 bunker flow on iOS (no Amber equivalent — NIP-07 via Safari extension or bunker-only)
• Test biometric auth on iOS (Face ID / Touch ID)
• Splash screen and app icon configuration
• TestFlight distribution setup

Considerations

• No NIP-55 (Amber) on iOS — need to ensure bunker flow is solid
• Safari WebView quirks (WebSocket handling, localStorage limits)
• App Store review guidelines for Nostr/Bitcoin content

Acceptance Criteria

• iOS app builds and runs on simulator
• Auth works (NIP-46 bunker + nsec at minimum)
• Publish and read flows functional
• Safe areas properly handled
• TestFlight build distributed
