feat: redesign review panel action hierarchy

- Download stays primary (full-width button)
- Save to Files demoted to subtle text link below download
- "Adjust settings" and "New file" are side-by-side compact buttons
- "Back to Tools" faded to very subtle (breadcrumb handles this)
- Clearer visual hierarchy: primary -> secondary -> tertiary actions
