/**
 * Dequeues Elementor scripts and styles for FunnelKit Builder pages
 *
 * This function prevents loading unnecessary Elementor assets on FunnelKit Builder pages
 * that are using canvas or boxed templates but not built with Elementor. This helps
 * improve page load performance.
 *
 * The function checks:
 * 1. If Elementor locations exist
 * 2. If current post exists and is valid
 * 3. If post type matches FunnelKit Builder types
 * 4. If page template is canvas or boxed
 * 5. If page is NOT built with Elementor
 *
