Fix critical bug: Award XP on multi-HP duck hits

- Fixed issue where players weren't getting XP when hitting (but not killing) multi-HP ducks
- XP was calculated but never added to player's total
- This bug could cause bot failures with new multi-HP duck types
- Now properly awards XP on each hit and saves to database
