fix: Disable SSL for PostgreSQL connection

Resolved the issue "The server does not support SSL connections" by disabling SSL in the PostgreSQL connection configuration. Updated the `config/db.js` file to set `ssl: false`.

- Disabled SSL in `config/db.js`
- Ensured the application connects to PostgreSQL without SSL
