What does this PR do?

When the question tool presents multiple questions in a batch, switching to another session and back resets the UI to question 1 with all answers lost. This happens because SessionQuestionDock is rendered inside <Show keyed>, so navigating away unmounts it and navigating back remounts it with fresh local state (tab: 0, answers: []).

This adds a module-level cache keyed by question request ID that saves in-progress state (tab, answers, custom, customOn) on unmount and restores it on remount. The cache is cleared after a successful reply or reject so stale drafts don't linger.
