Add TestSecurityConfig for improved test setup and update configurations

- Introduce `TestSecurityConfig` to simplify JWT usage in test environments.
- Update integration tests to import `TestSecurityConfig`.
- Split environment-specific configurations into new `application-dev.yml` and `applications-prod.yml` files.
- Adjust `docker-compose.yml` for development-specific settings.
- Clean up redundant JWT properties in `application.yml`.
