QC-65: Owner shop profile API + settings UI + onboarding

[DarshanCode2005]

Summary

Owner shop profile API + settings UI + onboarding

Milestone: M3 Owner
Labels: backend, frontend, owner

Learn

• Shop visibility rules in lib/shops-list.ts (non-empty name filter)
• Owner-scoped PATCH patterns from lib/owner-products.ts
• Cloudinary upload reuse from QC-34

Build

• Add GET/PATCH /api/owner/shop scoped to session shopId + ownerId
• Create lib/parse-shop-body.ts and lib/update-owner-shop.ts
• Route /owner/settings with form: name (required), description, address, categories, isOpen toggle
• Logo/cover upload via POST /api/upload (extend for shop assets folder quickcart/shops/{shopId})
• On first owner visit when shop.name is whitespace-only: redirect to /owner/settings?onboarding=1
• Dashboard/setup banner: 'Complete shop profile to appear in customer browse'
• Add ownerSettings to lib/routes.ts
• Script scripts/test-owner-shop-api.mts

Files

• app/api/owner/shop/route.ts
• lib/parse-shop-body.ts
• lib/update-owner-shop.ts
• app/(owner)/owner/settings/page.tsx
• components/owner/ShopSettingsForm.tsx
• lib/routes.ts
• scripts/test-owner-shop-api.mts

Acceptance criteria

• Owner sets shop name + isOpen from UI without touching MongoDB manually
• Shop appears on GET /api/shops after name is set
• Empty-name owner redirected to settings on dashboard/inventory/orders visit
• Cross-owner shop PATCH returns 403
• Closed shop (isOpen: false) still listed but checkout blocked

Depends on

• QC-17: Owner signup creates Shop stub #119 (QC-17)
• QC-34: Image upload route + storage #36 (QC-34)
