feat(nav): FAQ shows all 8 sections + drag-drop reorder in Settings

FAQ sections were only 4 (service/crm/depozit/finante) even though
the sidebar has 8. Added the missing 4 to Hints::AREAS with proper
icons + accent colors:
  📊 Analiză (pink)   📣 Marketing (orange)
  🛒 Magazin (cyan)   ⚙️ Admin (slate)

Retagged 15 hints that were shoved into wrong areas as a workaround
(admin.*/marketing.*/shop.*/analytics.* now use the matching bucket).
FAQ blade reads accent color from the AREAS registry instead of a
hardcoded local map.

Also added per-tenant navigation group ordering:
- Settings → new "Ordine meniu lateral" section with a Filament
  Repeater that has reorderable buttons (drag/arrow buttons) but no
  add/delete (fixed list of 8 groups)
- Persisted to settings.nav_group_order as an array of keys
- New ConfigureNavGroups middleware (runs after ResolveTenant on
  the web stack) reads the current tenant's order and calls
  $panel->navigationGroups([...]) so the sidebar renders in that
  order per-request
