Moderne licensed

Modernize Kotlin test code

Recipe IDorg.openrewrite.kotlin.testing.Testing$KtRecipeArtifactio.moderne.recipe:recipes-kotlin

Find Kotlin-specific test patterns: mockito-kotlin usage where mockk would be idiomatic, deprecated runBlocking / TestCoroutineDispatcher patterns, Kotest assertion migration candidates, empty / assertion-less / many-assertion test bodies, snake_case test names, and Hamcrest call sites that fluent assertion libraries (AssertJ, Kotest) replace cleanly. Each match is a SearchResult for review — nothing is rewritten automatically. For bulk JUnit 4 → JUnit 5 annotation/assertion migration, apply JUnit4to5Migration from rewrite-testing-frameworks.
