feat(faq): visual redesign — hero, chip toggles, 2-col colored cards

Replaced the flat vertical list with:
- Hero strip (gradient blue) with title, subtitle, and 2 stat pills
  showing total topics + section count
- Controls bar in a card: search input with inline icon, pill-shaped
  toggle button (green when hints ON), reset button with icon
- 2-column responsive grid of area cards. Each card has a colored
  header (service=blue, crm=purple, depozit=amber, finante=green)
  with icon + name + count badge
- Details/summary items use +/− indicators, tinted background when
  open, hover state; body has pill-styled links and green next-step
- Full dark-mode support
- Empty state with search icon

Same content, much easier to scan and looks like a proper help center.
