### What changes were proposed in this pull request? Adds a unit test spec for `PekkoMessageTransferService` in the amber engine, targeting Codecov-missed lines (no production code changes). Covers getAllUnAckedMessages, the backpressure toggle (both directions via flow-control credit), and the scheduled resend callback, using a real ActorContext from Pekko TestKit (no Mockito). ### Any related issues? Part of the ongoing amber unit-test coverage push toward the 80% target. ### How was this PR tested? `WorkflowExecutionService/testOnly *PekkoMessageTransferServiceSpec` passes locally (plain-JVM Pekko TestKit; no Python worker, Arrow Flight, live DB/S3/HDFS/LakeFS/Iceberg, or cluster bind), along with scalafmt and scalafixAll --check. ### Was this PR authored (partially or fully) using generative AI tooling?
