feat: add node/status filters and custom date range to traffic page

- Add NodeFilter component with flag emojis and checkbox dropdown
- Add StatusFilter component with colored status dots
- Add custom date range picker (calendar toggle, from/to date inputs)
- Wire all filters to backend params (nodes, statuses, start_date, end_date)
- CSV export passes all active filters and date range
- Add displayNodes memo for table column filtering
- Add i18n keys for nodes, statuses, dates in ru/en/zh/fa
