NexoPass 1.3.0: Linux and Windows app, project split into shared/android/desktop

The PC app (Compose Multiplatform) uses the nexopass script's files, so the
window and the terminal share accounts, site lists and the app password.
Clipboard copies carry KDE's password hint. GitHub Actions builds the APK,
.deb, .rpm, .msi and a portable Windows zip, and checks that passwords
still match the script.
