Represents a UI5 Dashboard artifact that aggregates Tiles and Cards into a structured layout.
Dashboards serve as entry points for visualizing business contexts and overviews,
often composed of reusable UI5 elements. Each dashboard is associated with a static
or dynamic XML fragment that defines the layout structure in a format consumable by
the UI5 runtime (e.g., sap.ui.core.Fragment).
Implementations are responsible for providing a valid XML blade path which can be rendered
and injected into the SAPUI5 shell container or application shell.
