[LogsDB] [Stack 8.19.20-SNAPSHOT] [atlassian_cloud] Failing test daily: system test: default in atlassian_cloud.audit

- Stack version: 8.19.20-SNAPSHOT
- LogsDB: enabled
- Package: atlassian_cloud
- Failing test: system test: default
- DataStream: audit

Failure:
```
observed hit count 10 did not match expected hit count 5
```

First build failed: https://buildkite.com/elastic/integrations/builds/48096

Locate the atlassian_cloud integration's audit DataStream system test named "default" and reproduce it with LogsDB enabled on stack 8.19.20-SNAPSHOT. Start from the failing assertion and the referenced Buildkite run, then determine why 10 hits are observed instead of 5. Done means the test passes consistently with the intended hit count.
