Template:Category/display-header

Renders the header row for a SemanticSchemas category display table. Shows the category's display label (or name as fallback).

Visual styling (background, alignment) lives in `resources/ext.semanticschemas.basecontent.css` keyed off the `source-semanticschemas-section-header` class.

Parameters:

• category - The category name (without namespace prefix). Required.
• label - Optional baked display label. When set, skips the

            `#show:Category:X|?Display label` lookup. Auto-generated
            dispatcher templates pass this.
