fix(gui): limit Files & Media collapsible child height to reasonable max

The begin_child() was using (0, -40) which made it stretch to fill parent.
Changed to (0, min(len(items) * 30 + 50, 300)) so it:
- Sizes to content (30px per row + 50px header)
- Caps at 300px max height
- Allows scrolling when content overflows
