fix: honor TCP maximum frame size in pipes

[tayfuryldz]

Fixes #8657.

Wires TcpSettings.MaxFrameSizeBytes into both transport pipes as minimumSegmentSize, preserving the existing input backpressure thresholds and output defaults. This restores the pre-pipeline setting semantics for larger configured frames without changing the default 4 KiB behavior. Also corrects the constructor/property wording to match the existing 1x validation.

Validation: git diff --check. Dependency restore/build was not run to avoid an unapproved dependency download; CI provides compilation/test execution.

Thanks for the PR. This has been superseded by #8663, which fixes #8657 the same way (MaxFrameSizeBytes as both pipes' minimumSegmentSize) and also adds a regression test and the akka.conf documentation. It's already merged into dev, so I'm closing this one.
