Previously the Danger Zone was always expanded, unlike the Image Generation
and Text Generation sections which were collapsible.
Now:
- Danger Zone has a clickable header with warning icon + chevron
- Collapsed by default (consistent with other sections)
- Click to expand and reveal Clear Waveforms + Delete All buttons
- Chevron rotates on expand/collapse
- Red styling maintained for visual distinction
This keeps the settings modal clean and uncluttered by default.
