Follow medal in contest setting categories when export results

[cubercsl]

When export the result, follow medal categories in contest setting. This will be consistent with the results generated by the award API.

I think this config is only used with your contests,

Can you extend @nickygerritsen his tests with a ranking of your contest (with teams in the same sortorder with some eligible for medals?), otherwise we always get this kind of PRs.

Before we merge this I would like a specific test for such a scoreboard.

The test data are based on AwardServiceTest.

Also, I moved the existing wf data to a subdirectory so that I could use different datasets in my tests.

domjudge/webapp/tests/Unit/Service/AwardServiceTest.php

Lines 89 to 113 in 6a99afc

	// Now generate some scores. We will create the following solves:
	// (a numbers is the solve time or an x means not solved)
	//
	// Team | A B C D
	// -----+-----------
	// A | 1 5 10 20
	// B | x 2 3 x
	// C | x 2 3 x
	// D | x x x 12
	// E | x x x 13
	// F | x x x 14
	// G | x x x 15
	// H | x x x x
	// I | x x x x
	//
	// This means A is the overall winner, will get a gold medal and is the winner
	// of category A. It is also first to solve problem A.
	// B is second, so it also gets a gold medal. It is also first to solve problem B and C
	// C scored the exact same as B, so it also gets the same medals
	// D is the first to solve problem D and is the winner of category B. But will not get any medal.
	// E and F will get no awards at all.
	// G is the winner of category C and will get a bronze medal.
	// The reason G doesn't get silver is that C would get silver if it was ranked differently,
	// but it is not.
	// H and I didn't solve anything, so it will not get any medals at all

It's not really defined what order this file should be in, nor what should happen when some categories have no medals. It looks a bit weird like this, but I think this is the best we can do,

Tests were added so I'm fine with it.
