Add ability for super admins to see recommendation code

[Nautman]

It would be great if super admins could see the recommendation codes in the /application/:userID/recommendation request. Then they would be able to upload recommendation letters from people that are unable to.

For what it's worth, here is the code that should be changed, and my suggestion what it should be changed to.

infrarays-api/src/api/controllers/application.ts

Lines 134 to 144 in 1b3f62f

	async function getRecommendations(req: Request, res: Response): Promise<void> {
	const userID = req.params.userID;
	const recommendations = await req.services.Application.getRecommendationsForApplicant(userID);
	const recommendationsReturn = recommendations.map(recommendation => {
	return req.services.Application.toRecommendationForUser(recommendation);
	});
	res.json(recommendationsReturn);
	}

const isAdmin = req.user?.type === UserType.Admin || req.user?.type === UserType.SuperAdmin;

const recommendations = await req.services.Application.getRecommendationsForApplicant(userID); 

if(isAdmin) return res.json(recommendations);

...

I'd just like to point out that perhaps you only want super admins to be able to see the code since that would effectually let them upload a file - which is not within the description of an admin.
