Generate realistic seed data for testing

Generate a Node.js seed script (`seed.js`) that populates a database with realistic, high-quality mock data for the following models: [describe models, e.g., User, Product, Order]. The script must: 1. Generate at least 10 entries per model with relations mapped correctly. 2. Use realistic names, emails, dates, and amounts (avoid simple 'test1', 'test2' strings). 3. Use standard Node.js imports and handle client initialization. Explain how to run it.
