Add awaitility module: testing async @Async/@Scheduled/@KafkaListener code without Thread.sleep

Covers replacing Thread.sleep with await() across a void @Async method, an
@EmbeddedKafka-backed @KafkaListener, and an already-running @Scheduled job;
verifies Awaitility 4.3.0's real defaults (10s timeout, 100ms poll interval)
and its default-uncaught-exception-handler swap directly against the jar;
and documents a real pom.xml trap where Boot 4.1.1 split Kafka's
autoconfiguration (spring-boot-kafka) out of spring-kafka itself, which
silently leaves @KafkaListener beans with no running container.
