Fix question prompt not rendering for active session

[thrawn-sh]

currentQuestion was the first pending question globally across all sessions. When another session had the first question in the flat list, the QuestionPrompt would not render for the session being viewed even though it had its own pending question.

Add getForSession() to the questions context and use it in SessionDetail to look up questions scoped to the current session.

sessionId is defined, returning null otherwise. Keep the existing
