feat: Upgrade JDK to Java 21 (#55)

* Migrate project to Java 21

- Upgrade Hive metastore 2.3.9 -> 4.0.1 and Apiary Extensions 6.0.2 -> 8.1.15
- Add hadoop-client-runtime:3.3.6 to provide shaded WoodStox XML parser classes
- Upgrade Spring Boot 2.7.10 -> 3.4.13 (Spring Framework 6.1)
- Migrate javax.annotation.PreDestroy -> jakarta.annotation.PreDestroy
- Exclude DataSourceAutoConfiguration to suppress Hive transitive JDBC drivers
- Upgrade Guava 27.1-jre -> 33.4.0-jre, MSK IAM Auth 1.1.9 -> 2.2.0
- Drop explicit Dropwizard/JUnit/Mockito/AssertJ/Logback/Log4j version pins (Boot BOM manages)
- Set jdk.version=21 and maven.compiler.release=21
- Upgrade Spotless 2.4.1 -> 2.43.0 (Java 21 compatible, google-java-format 1.19.2)
- Upgrade JaCoCo 0.8.6 -> 0.8.12 and Surefire 3.0.0-M5 -> 3.2.5
- Add .mvn/jvm.config with --add-exports for google-java-format on JDK 21
- Add Surefire --add-opens argLine for Hadoop/Hive/Mockito runtime reflection
- Update Docker base image openjdk:8-jdk -> eclipse-temurin:21-jre
- Add Jib container --add-opens JVM flags for Hadoop/Hive runtime
- Update GitHub Actions workflows: Java 21, temurin, checkout@v4, setup-java@v4
- Fix Hive 4.x API changes: HMSHandler constructor, event constructors, JavaUtils package
- Migrate commons-lang -> commons-lang3 (StringUtils)
- Replace deprecated org.awaitility.Duration with java.time.Duration
- Upgrade SpotBugs plugin to 4.8.6 for Java 21 compatibility
- Switch JDK distribution from Eclipse Temurin to Amazon Corretto
- Change Docker base image to Amazon Corretto on Amazon Linux 2023

* Fix integration tests: add Hive 3.x/4.x compatibility shims

apiary-hive-events:8.1.15 was compiled against Hive 3.x and is
incompatible with hive-metastore:4.0.1 at runtime. Three layers of
incompatibility are resolved via classpath shims in drone-fly-app:

1. HiveMetaStore.java: re-introduces HiveMetaStore$HMSHandler as an
   inner class (removed in Hive 4.x, now a standalone HMSHandler).
   Required by Json... (continued)
