Fix batch confirm: modal overlay + positioned beside button

Replace showCenterConfirm with showBatchConfirm(btn,message,callback) that creates a transparent modal overlay (z-index 9999) to block background clicks, positions the confirm dialog beside the trigger button. Updated all callers (batchDelete, batchPermanentDelete, permanentDelete, emptyTrash) to pass the clicked button. Added CSS for batch-confirm-overlay backdrop.
