Project refactor

[BurningSquid]

Touched on a lot of the elements of the project but here are some of the main categories:

1. Restructured project to match PEP guidelines (i.e. src/ folder with module). This includes dunder main and dunder init files
2. Conftest.py for pytest fixtures
3. Made Computer class more python with property getters instead of external get methods
4. Aligned python file names with class names
5. Added constants
6. Ubiquitous comments on changes made with REVIEW: tag for ease of use
7. .env file for PORT and HOST definition
8. .vscode settings and launch files for project setup
9. javascript refactoring and changes
