Remove Newsletter

Steps

1. Delete directories and files:

   • app/api/newsletter/ (subscribe/unsubscribe endpoints)
   • hooks/core/use-newsletter.ts (client-side newsletter hooks)
   • Newsletter section component from components/ (search for newsletter)

2. Update Prisma schema (prisma/schema.prisma):

   • Remove the NewsletterSubscriber model

3. Disable the feature flag: Set NEXT_PUBLIC_ENABLE_NEWSLETTER=false in .env, or delete the line from lib/config/features.ts.

5. Run pnpm db:push to sync the schema.
