chore: change seed script to use compiled JS instead of ts-node

- Update package.json to run node scripts/seed.js instead of ts-node scripts/seed.ts
- Rewrite seed.js to use compiled model from dist/ directory and Sequelize directly
- Add proper error handling and database connection setup
- Ensure script works after build, requiring npm run build first
