Consider adding max line length to .editorconfig

[ErlingHauan]

Description

Currently, maximum line length is not set in /backend/.editorconfig
If the developer accidentally has triggered autoformatting in their IDE, this can trigger unintended line breaks.

Issues with this:

• Can waste time if the developer has to revert the unintended line breaks
• Can make existing code harder to read
• Can make the diff on GitHub hard to read

Suggestions:

• Set max_line_length = off. The developers can then decide the line width themself, without worrying about autoformatting
• Set max_line_lenght = 200 This will enforce a collective maximum linewidth, while still leaving ample room for the developer regarding where to put the line breaks

Potential cons:

• If the developer has their preferred line length set in the IDE, it will be overrun by the .editorconfig file
