Remove Payments

Steps

1. Delete directories and files:

   • lib/payments/ (payment provider abstraction)
   • app/api/billing/ (checkout, portal, subscription endpoints)
   • app/api/webhooks/ (LemonSqueezy/Polar webhook handlers)
   • hooks/core/use-billing.ts (client-side billing hooks)
   • app/(dashboard)/dashboard/billing/ (billing settings page)

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

   • Remove the Plan enum (FREE, STARTER, PRO, ENTERPRISE)
   • Remove the SubStatus enum (INACTIVE, ACTIVE, TRIALING, etc.)
   • Remove these fields from the User model: plan, subscriptionStatus, customerId, subscriptionId, planPeriodEnd

3. Clean up config:

   • Delete lib/config/pricing.ts
   • Remove pricing-related nav links from siteConfig in lib/config/site.ts

4. Remove env vars: PAYMENT_PROVIDER, LEMONSQUEEZY_*, POLAR_*

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