Add iOS support for custom API IP configuration

Extend custom API IP feature to iOS platform with platform-appropriate defaults:
- Android: Defaults to 10.0.2.2 for emulator, custom IP for physical devices
- iOS: Uses localhost for simulator, custom IP for physical devices
- Added npm scripts for iOS custom IP builds (dev:custom, test:custom)
- Updated documentation to cover both platforms with examples
- Consistent --api-ip parameter across Android and iOS build scripts

Usage:
  ./scripts/build-ios.sh --dev                    # Default localhost
  ./scripts/build-ios.sh --dev --api-ip 192.168.1.100  # Custom IP

scripts/build-ios.sh
