feat: Update database schema and migration scripts

- Added new migration scripts for the `users` table, replacing the deprecated `users_table`.
- Updated `package.json` with new database commands for generating, pushing, and migrating schemas.
- Enhanced `README.md` with instructions for database migration and deployment.
- Refactored database connection handling to use a connection pool for improved performance.
