Remove dead dependencyManagement entries and unused version properties

Drop entries that are not pulled by any reactor module's resolved
dependency tree (verified via mvn dependency:tree across all 40 default
reactor modules):

- joda-time:joda-time (no source code references)
- org.glassfish:javax.el (jakarta-el.version) - jetty/jersey use jakarta now
- org.checkerframework:checker-qual - guava 33 swapped to jspecify
- org.slf4j:slf4j-log4j12 - superseded by log4j-slf4j2-impl
- org.apache.activemq:{activemq-broker, activemq-mqtt, activemq-kahadb-store}
- org.apache.hadoop:{hadoop-hdfs, hadoop-mapreduce-client-core,
  hadoop-yarn-common, hadoop-yarn-server-resourcemanager,
  hadoop-yarn-server-applicationhistoryservice,
  hadoop-yarn-server-web-proxy, hadoop-yarn-registry, hadoop-archives}
- org.ow2.asm:{asm-commons, asm-tree, asm-util, asm-analysis}

Also drop orphaned version properties:
azure-eventhubs.version, activation-version, hdfs.version (alias of
hadoop.version), jakarta-el.version, checker-qual.version, joda-time.version

Verified: mvn validate passes; resolved dependency trees identical
before and after the cleanup.
