feat(test-app): add iOS project structure and configuration

- Add iOS .gitignore for Capacitor iOS project
- Add Podfile with DailyNotificationPlugin dependency
- Add Xcode project and workspace files
- Add AppDelegate.swift for iOS app entry point
- Add Assets.xcassets with app icons and splash screens
- Add Base.lproj storyboards for launch and main screens

These files are generated by Capacitor when iOS platform is added.
The Podfile correctly references DailyNotificationPlugin from node_modules.
