Merge branch 'feature/falcon-PS9' into feature/extra-features

Resolved a Fatal Error occurring during AJAX product listing requests (e.g., price slider).

- Issue: In PHP 8.2+, accessing properties of a 'CategoryLazyArray' object
  using array syntax (dot notation) triggers a Fatal Error.
- Cause: The Faceted Search module returns a LazyArray object during
  XHR requests, whereas standard page loads provide a native array.
- Solution: Implemented a normalization block using JSON serialization
  to flatten the object into a standard associative array. This ensures
  template syntax compatibility regardless of the request type or
  property visibility (protected vs public).
