Child URL mappings for multi-language variants.

Structure: Array of language-specific URL objects

Purpose:

Stores language-specific URL paths for the same logical page
Enables internationalized SEO with localized URLs
Maintains parent-child hierarchy for URL organization

Population Rules:

Empty array when multi-language mode is disabled (Source: Static System Configuration)
Empty for dynamically resolved URLs (no stored children)
Empty for child URLs themselves (prevents nesting beyond one level)
Populated for parent URLs when language-specific mappings exist

Child Object Structure: Each child contains pk, new_path, and language fields. Children inherit routing metadata from their parent, so they don't duplicate func_module, func_name, etc.

Example: A parent English URL /products/shoes/ might have children:

Turkish: /tr/urunler/ayakkabi/
Arabic: /ar/منتجات/أحذية/
German: /de/produkte/schuhe/

This architecture enables one database record to manage multiple language-specific URLs.
