Implement Testing For PHP And TypeScript

[Toxocious]

With how large the codebase is, we may as well slowly work on implement testing.

I imagine this will be a relatively slow process, especially with how I'd prefer to resolve some of the currently open issues before working on this one.

Currently looking at Pest for PHP testing and Jest for TypeScript testing.

honestly probably never going to do this even though it's "good practice"

will remain open but low priority
