fix: turn check runs independently of evaluateDecision

Turn order should be enforced for ALL messages, not just non-human ones.
Previously, human messages bypassed turn check because they go through
human_list_sender path with shouldUseNoReply=false. Now turn check
always runs when channel has turn state.
