test: settle the post-response composer before seeding; give the TPA recorder adapter its infra helper

submitPlanSeed accepted a stale empty composer when the transcript recorded
end_turn before the CLI repainted (late-repaint-typed-current fails 5/5 on the
old helper, passes 5/5 now). The TPA recording fixture extracted recordE2E
without isPreTurnInfraFailure, so every failed case threw before recording.
