fix(phase1.4): move level-up logic OUTSIDE setScore to prevent multiple triggers

- Call setLevel() BEFORE setScore(), not inside the callback
- This prevents setScore from being called multiple times per food
- Level up happens once, then score is updated with correct points
- Fixes: 1st food +1pt (lvl1), 2nd food +2pts (lvl2), 3rd food +3pts (lvl3)
- No more duplicate level ups on same food
