Gate active batch additions on cleanup persistence

Route folder-monitor and hoster-selection additions through the shared active-batch start path so revoked source-cleanup confirmations are durably saved before Main receives any new job. Add real Electron coverage for blocked persistence, ordered success, and rejected saves across both entry points.
