feat(admin-remnawave): auto-refresh overview, responsive mobile grids, wide sub-requests

- Auto-refresh the recap/devices/top-consumers/subscription-requests widgets
  on a 60s timer (system + health already refreshed) so the page updates itself
- Mobile: a lone trailing stat card now spans the full row (no empty gap when
  the 2-column grid reflows)
- Subscription requests: full-width card with a two-column breakdown and a total
  count, instead of a half-empty narrow card
