Refactor docker

I've been working on some refactorings for this project. I restructured the project to be more Docker-friendly and made some updates to the configuration files. In the process, I also removed some files that are no longer being used, which should help with code cleanliness. I've tested this locally and everything seems to be working correctly. I'd appreciate it if you could take a look and let me know if you have any questions or concerns. Thanks!
