chore: cleanup all test files

[Parkreiner]

No issue to link – this is just something I thought I could fix really quickly while working in the codebase.

Changes made

• Removed all unused imports, and made sure type imports were labeled correctly
• Updated all comparisons to be more strict
• Simplified loops to remove unneeded closure functions
• Removed all explicit any types
• Updated how strings were defined to follow general TypeScript best practices

Notes

• We definitely want some kind of linting setup for this repo. I'm going to bring this up when Blueberry has its next team meeting next week

I left a comment to prevent any possible merge conflicts for #287. Otherwise all look good to me.

@Parkreiner, all modules are merged. You may continue with the refactoring here,

We only have the runtime logic in the windows-rdp module, right?

[Parkreiner]

Right now, yeah

But one of the other benefits of having an older compilation target is that, because I have that JavaScript file set up to be part of the TypeScript project, the TypeScript LSP can catch any function calls that might be using features that are too recent

For linting, let us use biomejs, which is similar to a coder/coder. I am using biome vscode extension that does help catch these errors.
