feat: improve header responsiveness and update seed initialization

- Add text truncation for title on mobile screens
- Hide user info section on mobile, show simplified icons only
- Update seed.ts to create admin and demo users with proper password hashing
- Add bcryptjs for password hashing in seed script
- Update QWEN.md documentation with seed command and default users
