Done! The responsive overflow issue is fixed: (#1193)

**Changes made:**
1. Container now stacks vertically on mobile (`flex-col gap-2`), horizontally on `sm+` screens
2. Removed the spacer that was causing the overflow
3. Both "Run Setup" and "Try Again" buttons are full-width on mobile, auto-width on larger screens
4. Icon buttons push to the right on desktop with `sm:ml-auto`

The Try Again button will no longer overflow on small screens.
