feat: Add shift-click to append suggestions to text area (#2081)

* feat: Add shift-click to append suggestions to text area

When a user shift-clicks a suggestion, the text is now appended to the current text area content instead of being sent immediately. This allows users to:
- Build complex prompts by combining multiple suggestions
- Edit suggestions before sending them
- Reuse parts of previous suggestions

The implementation passes the mouse event through the component chain and checks for the shift key before deciding whether to append or send the message.

* Tweak icon and internationalize
