fix: ensure Prisma client generation and migrations in Docker build

- Add explicit  step in both builder and runner stages
- Set DATABASE_URL environment variable for Prisma operations during build
- Run database migrations during build to support static page generation
- Copy package-lock.json to runner stage for production dependency installation
- Fix the original TypeScript error: Module '@prisma/client' has no exported member 'Event'
