feat: add all components as regular directories (remove nested .git)

- lastochka-server: removed nested .git, now browsable on GitHub
- lastochka-ios: removed nested .git, now browsable on GitHub
- lastochka-android: added (Kotlin + Jetpack Compose)
- lastochka-desktop: added (Electron + React)
- lastochka-android-compose: removed (replaced by lastochka-android)
- lastochka-ui: updated to latest prototype
- .gitignore: added .gradle/, Pods/, DerivedData/, local.properties
