fix: serve variant images via custom endpoint instead of product URL

Browse Source 
Product image URL was serving placeholder because writing to image_1920
doesn't work for variants (computed field). New approach:
1. Store image in wizard line table (attachment=False, bytea column)
2. Serve directly via /woo/image/{line_id}/{filename} endpoint
3. WC downloads real image data from this URL
4. Also saves to image_variant_1920 for Odoo reference
