CngxDialogStack

Tracks open dialog instances as a stack for backdrop management.

Provided in root - always available, no manual provider setup needed. When multiple modal dialogs are stacked, only the topmost shows its ::backdrop. Each CngxDialog reads isTopmost from this service to control --cngx-dialog-backdrop-opacity.
