RadzenTabs: handle JSDisconnectedException during tab selection

Browse Source 
Wrap the JS interop calls in SelectTab, SelectTabOnClient and
OnAfterRenderAsync with try/catch (JSDisconnectedException) so a
dropping SignalR circuit no longer throws an uncaught exception and
leaves multiple tabs visually active. Matches the existing pattern
used by RadzenToc/RadzenChart.

Fixes #2558
