- Add src/lib/meshkee.ts API client for the live backend
(https://api.meshkee.com, tenant aradarisman.com)
- Products list/detail pages now fetch real catalog data,
images, categories and pricing instead of static mock data
- Blog list/detail pages fetch from /tenants/{domain}/blogs
with a graceful empty state since no posts are published yet
- Allow the Meshkee media CDN host in next.config.ts
- Remove now-unused static src/data/products.ts and posts.ts
