### Description
Adds KafkaIngestionWithCompactionTest to reproduce a bug where realtime
pending segments are not upgraded after minor compaction.
The bug: When minor compaction replaces V1 historical segments with V2, the
overlord should call registerUpgradedPendingSegment on active realtime tasks to
re-announce their pending segments at V2. In this scenario, that upgrade never
happens, the log `==== StreamAppenderator: announcing upgraded realtime
segment` is absent, meaning the slow supervisor's rows become invisible to
queries once V1 segments are superseded.
Test setup:
- fastSupervisor (3s task duration): commits segments quickly
- slowSupervisor (100s task duration): holds an append lock throughout,
never commits during the test window
- After Step 2 full compaction and Step 3 ingestion, minor compaction
triggers in Step 4
- Expected: slow supervisor's 20 realtime rows remain visible at V2; test
observes them missing
When the bug is present, assumeTrue passes and the test proceeds to a
success, we've verified the buggy behavior end-to-end.
