chore: readability and useless code

[mafewtm]

Description

Overall just fixing the god awful readability but more details are below:

• Add new lines, table separation, indentation, and undo unnecessary one line if statements for readability
• Use the colon syntax for formatting strings
• Use if or if not instead of == nil or ~= nil
• Use cache.resource instead of GetCurrentResourceName()
• Add name and fix description in manifest
• Modularize server/finance.lua
• Fix the requiring of server/finance.lua
• Remove unnecessary localizations

and probably a few other things too

Checklist

good work as always :)

I've had issues with waitFor and this. I believe it needs to return nil implicitly if the condition hasn't been met. Maybe explicitly would work as well, but the way it was done before will definitely work.

else not needed as default behavior is implied return nil
