Enhance database management with cleanup and reset scripts

- Added a new database cleanup script to remove all data while preserving the schema, facilitating a clean state before seeding.
- Updated package.json to include new commands for database cleaning and resetting.
- Modified schema definitions to use an array format for index and constraint definitions, improving clarity and consistency.
- Updated product seeding logic to utilize role-based assignments directly from mock data, enhancing flexibility in product-role relationships.
