Pull request overview

Backport to stable/8.8 that aims to reduce archiver integration-test flakiness when tests share an OpenSearch cluster by scoping test data per run, reducing cluster-wide operations, and making retention/ISM handling less contention-prone.

Changes:

• Introduces a per-test testPrefix in the archiver IT base class, uses it for index prefixing and more targeted refreshes, and increases wait timeouts via a shared ARCHIVE_TIMEOUT.
• Reduces OpenSearch pressure by refreshing only prefixed indices and setting numberOfReplicas=0 for test-created indices.
• Reworks OpenSearch archiver repository IT cleanup to delete only test-owned indices/policies instead of deleting *.

File	Description
zeebe/exporters/camunda-exporter/src/test/java/io/camunda/exporter/tasks/archiver/UsageMetricsArchiverJobIT.java	Uses scoped refresh (refresh(testPrefix)) and shared timeout to reduce cluster-wide operations and flakiness.
zeebe/exporters/camunda-exporter/src/test/java/io/camunda/exporter/tasks/archiver/StandaloneDecisionArchiverJobIT.java	Same scoped refresh/timeout approach for decision archiver tests.
zeebe/exporters/camunda-exporter/src/test/java/io/camunda/exporter/tasks/archiver/OpenSearchArchiverRepositoryIT.java	Switches from global cleanup to per-test unique IDs and targeted deletion of indices/policies.
zeebe/exporters/camunda-exporter/src/test/java/io/camunda/exporter/tasks/archiver/ArchiverJobIT.java	Adds per-test index prefixing and replicas=0 to reduce cross-test collisions and shard readiness issues.
