frontend: мобильная версия отключена

- Удалён /mobile-роут и MobileFormPage; " /" всегда ведёт на /desktop
  (user-agent/width-детекция выпилена — ЦОУ работает только на десктопе).
- Тема mobile в index.css оставлена (мёртвый CSS, не мешает).
- CaseForm.isMobile не тронут: DesktopSARPage передаёт false явно.
