Pass preferences to BrowserWindows via command line arguments

[araujoarthur0]

Context / Background

The 3 browser windows we create from main start by doing a reverse call back into main to ask for the user preferences.
The idea of this PR is to pass the preferences as a stringfied JSON via the command line arguments of the Browser Windows. They can be retrieved on the renderer preload scripts from window.process.argv. That should speed up creation of windows and allows us to remove the ipcRenderer dependency function to get user preferences from the renderer.

What change is being introduced by this PR?

• Passing in JSON preferences via args to browser windows. Picking up on renderer and using on $() functions
• Creating a renderer-api.mjs file with reusable API functions between the 3 windows. Renamed the exposed APIs to have matching names per API.
• Updated tests to match the new settings.
• Removed ipcRenderer dependency inside preferences.mjs and some Promise methods.

How will this be tested?

App is working fine, tests are passing.

Something is off, when testing, my workday waiver manager never gets the black theme applied (the same doesn't happen for the preferences).

Weird, for me it's appearing dark. Do you see any errors in the dev tools console?
