[To dev/1.3] [Pipe] Stabilize compression integration test (#18644)

[Caideyipi]

Description

Backport the applicable compression-test fix from #18644 (2838c35317ff4c0fda0eaec78b141d08d6ee34d0) to dev/1.3.

IoTDBPipeSinkCompressionIT issued six rapid writes to the same time series with now() timestamps. Because timestamps have millisecond precision, multiple writes can receive the same timestamp and be deduplicated, leaving the final row count below eight. This change uses deterministic timestamps 3 through 8 instead.

The upstream commit also updates IoTDBShowReceiversIT. That test and its SHOW RECEIVERS feature are not present on dev/1.3, so that part is intentionally omitted. The compression test also lives under the older autocreate package on this branch; the conflict was resolved at that path.

Verification

• mvn spotless:check -pl integration-test -P with-integration-tests: passed.
• git diff origin/dev/1.3..HEAD --check: passed.
• IoTDBPipeSinkCompressionIT#testCompression1 was attempted locally, but the integration-test module is currently blocked before execution by unrelated existing cross-module dependency errors (missing RepairDataPartitionTableProgressState, Jackson/Gson, and OPC UA classes). The corresponding targeted test passed in [Pipe] Stabilize receiver and compression integration tests #18644.
