admin: live query detail becomes a modal, live/history and period pickers become tabs and radios, client delete confirms in a dialog

the streamed-query detail panel is now a rac modal dialog with focus containment and restore. the live/history switch is rac tabs driven by the url, the overview period picker is a rac radio group, and the clients delete flow uses the shared confirm dialog; an authority turn keeps the dialog open and withdraws only the destructive action.
