fix(tui): add mouse/touch support to permission prompt buttons

[5p00kyy]

Summary

• Add onMouseOver and onMouseUp handlers to permission prompt option buttons
• Allows users to select "Allow once", "Allow always", or "Reject" via mouse click or touch input
• Selection follows cursor/touch on hover for visual feedback

Details

The permission prompt previously only supported keyboard navigation (arrow keys + enter). This change adds mouse/touch support following the existing pattern used throughout the codebase (e.g., dialog-confirm.tsx, question.tsx).

This is particularly useful for users running OpenCode in terminal emulators that support mouse/touch input (e.g., Termux on mobile devices).
