fix: mobile responsive improvements

- Audit: responsive summary cards (grid-cols-2 mobile, p-3), responsive empty states
- Repair-icons/sync-all: log area horizontal scroll (overflow-x-auto, whitespace-nowrap)
- Upload furni: tighter mobile padding (p-4 sm:p-5)
- Nitro client: compact toolbar on mobile (smaller buttons, tighter gap, top-2/left-2)
