People picker ListBox used MouseBinding which fires before SelectedItem
updates, causing null CommandParameter. Replaced with SelectionChanged
event handler in code-behind.
AuditUsersAsync created TenantProfile with empty ClientId, causing
ArgumentException in SessionManager. Added currentProfile parameter
to pass the authenticated tenant's ClientId through.
