Find Mono/Flux ergonomic smells

Recipe IDorg.openrewrite.kotlin.spring.FindMonoFluxSmells$KtRecipe

Artifactio.moderne.recipe:recipes-kotlin

Reactive-pipeline shapes that read more naturally a different way: flatMap { Mono.just(...) } → map, block() / blockFirst() / blockLast() outside @Test methods, single-argument Flux.subscribe (missing error consumer), raw throw inside operator lambdas (use Mono.error), Mono.zip (verify independent operands), and Flux.fromIterable(listOf(...)) (use Flux.just).
