Fix image upload structure for Miravia API compliance

🔧 Bug Fixes:
- Fixed product image structure to match Miravia API requirements
- Updated MiraviaProduct.php getData() method to wrap images in {"Image": [...]} format
- Updated MiraviaCombination.php getData() method to wrap SKU images properly
- Resolved error "[4224] The Main image of the product is required"

📋 Changes:
- Modified getData() methods to transform flat image arrays to nested structure
- Product images: images[] → Images: {"Image": [...]}
- SKU images: images[] → Images: {"Image": [...]}
- Maintains backward compatibility for empty image arrays

🎯 Impact:
- Product uploads will now pass Miravia's image validation
- Both product-level and SKU-level images properly formatted
- Complies with official Miravia API documentation structure
