Both Flow Debugger and Debug View enable the shared InstancePicker as soon as
_selectedSiteId lands, but Blazor renders at the site-change handler's first
await — at which point the picker is still holding the PREVIOUS site's Areas /
Instances lists. Typing into the field in that window (an operator, or
Playwright's FillAsync, which waits only for "enabled") was silently lost: the
picker compares both lists by reference, so the freshly-assigned lists read as
"the site changed" and it clears the field text and closes the panel.
Both pages now hold an _instancesLoading flag across the whole load — set before
the first await, cleared in a finally so a fault or a site-scope refusal cannot
leave the picker disabled forever — and fold it into the picker's Disabled
expression. InstancePicker itself is unchanged.

Task 5 review follow-ups:
- New DebugViewInstancePickerTests.WhileConnected_ThePickerIsDisabled pins that
a live connection locks the picker: both the input and the chevron carry
`disabled`. It marks the page connected by reflection, the way the other
DebugView page tests do (DebugViewAlarmTableTests) — driving the real gRPC
stream is not available to a bUnit render.
- OnInstanceSelectionChanged() was already a no-op and its comment described the
@bind that the picker replaced; deleted, and OnInstancePicked now just records
the id (XML-documented).
- The ItemLabel lambda is hoisted to a private static InstanceLabel(Instance),
passed as a method group.

The flat instance <select> on Debug View is replaced by the shared
InstancePicker area-tree combobox (design 2026-09-08 §3): the page now loads
the site's areas alongside its Enabled instances in LoadInstancesForSite and
hands both lists to the picker with ItemLabel = "UniqueName (State)",
Disabled="@_connected" and DataTestPrefix="debug-instance".
Both lists are now REPLACED rather than cleared in place wherever the site
changes (LoadInstancesForSite, StartFresh) — the picker compares Areas and
Instances by reference and a new object is what tells it the site changed.
The ?siteId=/?instanceId= deep link and the localStorage reconnect keep
setting _selectedInstanceId directly; the picker reads it on parameter set,
so both paths are unchanged.
