Extends the Planning Mode no-active-question fix to the other three
interview lanes: a LIVE session (no summary yet) that receives a
submission with no active question now reprompts the agent to continue
the interview and ask a fresh question — carrying the submitted input as
context — instead of throwing "No active question in session". Completed
interviews (summary present) still reject late submissions, preserving
the existing contract.
