fix: Return all obtained levels for badges

[cetteup]

I was wondering why I kept getting basic badges (level 1) in game even though I already had the corresponding badge with a higher level. Turns out the current implementation only returns the highest awarded level for badges due to the GROUP BY award_id + COUNT. The game server is thus told that I don't have the lower level badges yet, leading it to award the level 1 badge again.

The endpoint needs to always return all awarded levels of a badge. The query exploded in size a bit, but I didn't really see any alternatives. Medals require the GROUP BY to merge the individual rows into one containing the COUNT. But badges must not be grouped and ribbons don't really care (single row anyway). Hence the UNION of two different queries. I also moved setting first to zero from the write loop to the query and sorted the query results by award id and level to make the response easier to read.

Note: Performance does not seem to be impacted by the change.

Partially fixes #78

If you have already received Tier 2, for example Anit-Tank Silver. Do you keep getting Tier 1 (Bronze) again

I couldn't test the fix because I immediately found another serious error that made it impossible to check.

My bf2 account has all medals and badges.

When I spawn on the map I immediately get the Combat Infantry Medal and in loop, every second I always get the same medal until the end of the round.

Here my round bf2 server logs

my medal_data.py (default, I didn't make any changes)
