New shared DiffDialog mirroring ConfirmDialog's API
(ShowAsync(title, before, after)) so live-data pages stop
hand-rolling Bootstrap modal markup.
Topology: <h4> in flex header, aria-labels on Expand/Collapse/Refresh
and the inline rename input, Live-updates toggle (suppresses the 15s
timer when off), instance/area counts moved into a summary alert
above the tree, Stale badge paired with bi-exclamation-triangle icon
+ aria-label, hand-rolled Diff modal replaced with <DiffDialog @ref>.
Deployments: pause/resume auto-refresh button replaces the static
"Auto-refresh: 10s" text; summary cards switch to
col-lg-3 col-md-6 col-12; InProgress spinner gets role="status" +
aria-label; failed rows pick up a bi-x-circle icon next to the
Status badge; Deployment ID + Revision folded into one
{id}@{revision[..8]} cell; inline Error column collapses behind a
per-row "View error" toggle; bare empty-state text upgraded to the
centered muted block.
DebugView: status-strip card at the top showing instance / connection
state / last snapshot timestamp plus a "Start fresh" button when the
page auto-reconnected from localStorage. Per-table filter input,
scroll-lock toggle, Clear button, and a 200-row queue-style cap.
<tbody> elements gain aria-live="polite" aria-atomic="false" for
screen-reader announcements. Quality and Alarm-State badges get
aria-labels; timestamps display HH:mm:ss with full ms in a hover
tooltip. Auto-reconnect surfaces a toast with autoDismissMs: 8000.
