feat(cli): persist resolved approval/clarify prompts in scrollback (#44702)

Modal prompt panels (dangerous-command approval, clarify questions)
live in the prompt_toolkit layout and vanish on the next repaint,
leaving no trace of the question or the decision in chat history.

Emit a dim one-line summary after each prompt resolves:
  ⚠ Approval: <command> → allowed for session
  ? Clarify: <question> → <answer>

Gated on display.persist_prompts (default true). Detail and outcome
are whitespace-collapsed and capped at 120 chars.
