 * Migration: Add embed asset support
 *
 * Adds support for storing embed assets (360 panoramas, 3D models, iframes):
 * - Add 'embed' to asset_type ENUM
 * - Add embed types to type ENUM (embed_360, embed_3d, embed_iframe)
 * - Add embed_code column (stores full iframe HTML or direct URL)
 * - Add embed_provider column (extracted provider name: matterport, kuula, etc.)
