✨ improve: Update disabled action tooltips for better accuracy

Update tooltip messages from "正在生成中，请稍候..." to "操作暂时被禁用"
in MessageActions component to better reflect that actions can be disabled
during both message generation and editing states.

Changes:
- Replace specific "generating" message with generic "temporarily disabled" message
- Applies to retry, edit, role toggle, and delete action tooltips
- Provides more accurate user feedback for disabled states
