Fix product 2 image by normalizing deprecated catalog URLs

[aviramha]

Summary

Product 2 ("Team Work Makes The Dream Work T-Shirt") failed to show an image in the shop UI because the shared inventory database still stores a removed Cloudinary path (Metal Mart/samples/mirrord-hoodie-front) with a leading empty string in image_urls.

This PR repairs catalog responses at the inventory API layer and adds defensive filtering in the frontend image helpers.

Changes

• inventory-service: Normalize product rows before returning them from GET /products and GET /products/:id
  • Map the deprecated Metal Mart/samples/mirrord-hoodie-front path to the current front/back Cloudinary public IDs
  • Trim and drop blank entries from image_urls
  • Fall back to image_url when image_urls is empty
• metal-mart-frontend: Filter blank strings from image_urls in getImageUrls / getPrimaryImageUrl

Verification

Verified with mirrord (session: cursor-fix-product-2-image-f256) against the playground cluster:

• Filtered GET /shop/api/products/2 returns usable image_urls[0] (team_Work_makes_the_Dream_Work_-_front_w5qdnb)
• Unfiltered traffic continues to hit the cluster deployment (bad legacy data unchanged in DB)
• Playwright: 9/9 checks passed — product 2 detail hero image loads, no "No image" placeholders on /shop/products or /shop/products/2

Screenshots

Products grid — all 16 products show images, including product 2:
