Subject: [PATCH] fix(web): allow external images in Next.js Image component

Next.js restricts the `next/image` component to internal domains by default.
Configured `next.config.ts` to parse the `NEXT_PUBLIC_S3_ORIGIN` environment
variable and add it to `remotePatterns`, alongside Google Auth avatars, to
allow uploaded images to be properly optimized and displayed.
Also fixed a minor backend spec counting public routes and a nullish content
crash in the blog service.
