feat: update Printful client to v2 mockup-tasks API format

The v2 API uses products array with catalog source, nested layers in
placements, and GET /mockup-tasks/{id} for polling. Also removes
hardcoded domain in favor of PUBLIC_URL setting.

 <!-- SECTION:DESCRIPTION:BEGIN -->
 Current upload page uses client-side Canvas compositing with simple template images. When Printful API token is configured, enhance with real Printful Mockup Generator API (POST /mockup-generator/create-task) for photorealistic product previews showing actual garment colors and fabric texture.

+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+2026-02-21: Printful client code is DONE and deployed. Blocking issue: API token not scoped to store.
+
+What's done:
+- backend/app/pod/printful_client.py created (catalog, mockups, orders)
+- designs.py updated (Printful mockup path + Pillow fallback)
+- order_service.py refactored (provider-aware routing: printful vs prodigi)
+- Token stored at ~/.secrets/printful_api_token and in Netcup .env
+- Deployed to fungiswag.jeffemmett.com (Pillow fallback working)
+
+Blocking:
+- Token u5WU...R2d returns "This endpoint requires store_id" on mockup/order APIs
+- Need to create a NEW token on developers.printful.com scoped to "Fungi Flows" store
+- Select the store in the "Access" dropdown (not "Account (all stores)")
+
+Once new token is set, just update ~/.secrets/printful_api_token and Netcup .env, rebuild, done.
