feat: Enhance auth database setup and environment variable loading

This commit improves the setup of the authentication database by adding a new function to create necessary tables for both frontends. It also ensures that environment variables are loaded from a `.env` file before any database operations, enhancing configuration management. Additionally, minor updates are made to related scripts for better clarity and functionality.
