When the enricher adds extra angle images, sort them so front views
come first (position 0) and shift existing images down. This ensures
the product gallery leads with a proper front shot rather than a
handle-side or angled preview.
Also adds Products.update_product_image/2.

New PrintfulGenerator module creates demo products in Printful with
multi-variant support (multiple colours/sizes per product type).
Mix task gets --provider flag to choose between Printify and Printful.
After syncing Printful products, MockupEnricher Oban worker calls the
legacy mockup generator API to produce extra angle images (back, left,
right) and appends them as product images. Jobs are staggered 45s apart
with snooze-based 429 handling. Flat products (canvas, poster) get no
extras — apparel and 3D products get 1-5 extra angles each.
Also fixes:
- cross-provider slug uniqueness (appends -2, -3 suffix)
- category mapping order (Accessories before Canvas Prints)
- image dedup by URL instead of colour (fixes canvas variants)
- artwork URL stored in provider_data for enricher access
