Class RadzenBadge
A small label component used to display counts, statuses, or short text labels with semantic color coding. RadzenBadge is a compact visual indicator commonly used for notification counts, status indicators, tags, or highlighting important information. Supports multiple styles (Primary, Secondary, Success, Info, Warning, Danger, Light, Dark) for semantic coloring, variants (Filled, Flat, Outlined, Text) for different appearances, and shapes (standard rectangular or pill-shaped via IsPill). Content can be simple text via Text property or custom content via ChildContent. Can be absolutely positioned to overlay other elements (e.g., notification icon with count). Often used inline with text, on buttons (to show counts), or overlaid on icons (notification badges).
