✨ Implement dynamic image path and refactor Docker compose

With these changes, we have made two main modifications. Firstly, we have integrated a dynamic image path based on the environment's port. This ensures that each instance will have its own unique storage location, preventing potential overwrites and conflicts.

Secondly, there is a significant refactor of the 'compose.yml'. The 'nginx' configuration is removed, and instead, a new service named 'api2' is added. This change aims to simplify the setup and use a dedicated API instance with its port.

The rationale behind these changes is to enhance scalability, maintainability, and reduce complexities associated with the previous 'nginx' setup. Additionally, the dynamic image path will allow better flexibility when deploying multiple instances of the application.
