AlertRenderBase class abstract

Shared structural base for themed alert renderers.

Factors the identical build logic shared by every theme's alert renderer (the root container, the optional icon block, the content block with its title/description/child/action children, and the optional dismiss button) into one place. A concrete theme renderer only supplies the value-producing members below: the per-element CSS classes, the style maps, the default icon, the dismiss glyph and the action spacing.

The overall element tree is byte-identical across all three themes; only the CSS class strings and style values differ, so this base uses value-map abstractions (like the button and card bases) rather than structural sub-builders.

This base lives in core and depends only on core props; it must never depend on a theme package.
