- Switch Prisma schema from SQLite to PostgreSQL
- Add netlify.toml for Netlify deployment config
- Add @netlify/plugin-nextjs for serverless Next.js
- Remove Docker build files (Dockerfile, docker-compose, start.sh)
- Remove auto-healer and scripts directories
- Update next.config.ts (remove standalone output)
- Database: falah_mobile_v1 on Contabo Postgres
