Remove the Status column and row-level badges/actions; keep source-level
Editable on group headers. Double-click managed rows to edit; commit staged
drafts when focus leaves the row via isFocusOutsideElement in the shared
scroll-cue module. Hide inactive system-host rows when dnsmasq ignores them
and move system-hosts / expand-hosts notes below the content area.
Memoize VisibleGroups so BuildGroups runs once per render during search.
Move read-ethers metadata to the DHCP section; adjust Hosts page state copy
and related effective-config tooltips/builders where needed.
Redesign the Hosts page around source-aware grouped rows with shared table shell styling, fix effective-config save session synchronization, and move read-ethers into the DHCP model where dnsmasq actually applies it.
