feat: variant push wizard — review pricing, SKU, images before pushing

Replaced direct push with a wizard that shows all variants in an editable
table. User can review/edit standard price, sale price, SKU, and image
per variant before pushing. Include/exclude toggle per variant. Already
synced variants shown for reference. Geo-tags images if configured.
