CAMEL-22524: Add HazelcastRoutePolicy integration test
Create automated IT that tests HazelcastRoutePolicy leader election
using embedded Hazelcast. The test runs 3 concurrent nodes with
staggered startup, each with its own HazelcastInstance and route
policy, verifying that distributed lock-based leader election works
correctly and all nodes eventually execute their routes.
