fix(cli): improve ask_user_question tool handling and UI

Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

- In ACP mode: allow ask_user_question in YOLO mode (user must respond)

- In ACP mode: allow ask_user_question in plan mode for clarifications

- Hide footer when confirmation dialog is active

- Fix tab index overflow with functional state updates

- Fix ask_user_question detection in VSCode companion (use rawInput)

- Add cleanup for pending ACP promises on panel/provider dispose

- Use theme.text.accent consistently for highlighted elements

- Remove unused 'answers' param from AskUserQuestionParams

This ensures users can always respond to clarification questions

in ACP mode regardless of approval mode, and improves dialog UX.
