- SiteHealthGrid shows device cards with status dots, CPU/memory bars, uptime
- SectorFormDialog supports create and edit modes for sectors
- SiteSectorView groups APs by sector with collapsible sections, connected CPE lists, aggregate stats, sector assignment dropdown
- SiteLinksTab wraps WirelessLinksTable with siteId filtering
- Add sector_id and sector_name to DeviceResponse, site_id/sector_id to DeviceListParams
