fix: mobile/responsive issues in FAQ and info pages

- FAQ builder: touch targets 36px → 44px (move up/down/delete buttons)
- Filter tabs: add flex-wrap to prevent overflow on narrow screens
- Accordion: add ResizeObserver for dynamic content height (images
  loading, viewport rotation won't clip content anymore)
- Accordion: use stable key (index+question) instead of filtered array
  index — search+toggle no longer opens wrong item
