Fix Netty version conflict by adding Netty BOM and switching to Apache Cassandra driver (#2512)

This commit resolves the Netty version conflict causing LinkageError during startup.

Error:
    java.lang.LinkageError: Possible multiple incompatible native libraries
    on the classpath for libnetty_transport_native_epoll_x86_64.so
    Caused by: java.lang.NoSuchMethodError: Method
    io.netty.channel.epoll.NativeStaticallyReferencedJniMethods.isSupportingTcpFastopen()Z not found

Root Cause:
Multiple dependencies brought in incompatible Netty versions:
- Cassandra driver 3.11.3 (com.datastax.cassandra) declared Netty 4.0.44.Final (2016!)
- Infinispan 9.4.24 brought in Netty 4.1.51.Final
- o11yphant 1.9.2 brought in Netty 4.1.118.Final
- Various other dependencies brought in 4.1.77.Final and 4.1.100.Final

This version mismatch prevented Netty from loading native epoll transport,
causing fallback to NIO with warnings.

Solution (following approach used in path-mapped-storage):
1. Switched from com.datastax.cassandra to org.apache.cassandra groupId
   to match path-mapped-storage dependency (version 3.12.1)
   Note: Package names remain com.datastax.driver.* internally
2. Added Netty BOM version 4.1.118.Final to enforce consistent Netty
   versions across all modules (eliminates need for exclusions)

Changes:
- pom.xml: Added Netty BOM, switched to Apache Cassandra driver 3.12.1
- subsys/cassandra/pom.xml: Updated to Apache Cassandra driver
- addons/schedule/model-java/pom.xml: Updated to Apache Cassandra driver
- addons/schedule/common/pom.xml: Updated to Apache Cassandra driver

Result:
All modules now use Netty 4.1.118.Final consistently via BOM, eliminating
version conflicts and allowing native epoll transport to load properly.
