Add Kotlinx Kover test coverage calculator (#199)
* Add Kotlin Kover * Add AuthKtorConfiguration tests * Ensure at least 25% code coverage * Exclude Previews from code coverage * Specify Kover report path for SonarQube * Add Kover xml report task * Extract sonar to a separate step * Add some exclusions and minimum coverage * Exclude Hilt-generated classes * Add shopping list view model tests * Reduce the coverage requirement
