feat(adminui): ScriptLog live-pill bound to broadcaster health

Browse Source 
Subscribe ConnectionStateChanged before reading IsConnected (subscribe-then-read
idiom, matches DriverStatusPanel) so no transition is missed. Add
OnConnectionStateChanged handler that marshals to the circuit sync context via
InvokeAsync. Dispose unsubscribes both events.

Reconnect-overlay: App.razor loads _framework/blazor.web.js and contains no
custom #components-reconnect-modal element; .NET 10 Blazor's default reconnect
overlay is active automatically — no custom markup needed.

No unit tests; live-verify follows.
