chore: regen api-reference for spec.branding.cssConfigMapRef (#87)

The BrandingSpec field (spec.branding.cssConfigMapRef) was added in
e5da3ab but docs/api-reference.md was not regenerated, so the Docs Build
"verify api-docs committed" check fails. Run make api-docs and commit
the result.

+BrandingSpec configures optional UI brand theming. When set, the operator
+mounts the referenced ConfigMap into the Paperclip container and points the
+server at it via PAPERCLIP_BRAND_DIR. The server then serves the directory
+under /branding and loads /branding/brand.css after the bundled stylesheet,
+so the ConfigMap's brand.css can override the product's CSS variables without
+rebuilding the image.
