Allow reward bosses to have loot in both the corpse and Reward Chest

[williamkeske]

Would it be possible to adjust the reward boss system so that, when a boss is killed, its loot can be opened directly from the boss's corpse while still keeping the loot available in the Reward Chest?

Currently, bosses configured with rewardBoss = true only provide their loot through the Reward Chest.

The idea would be to support both methods at the same time: allow players to open and collect loot directly from the boss's corpse, while preserving the existing Reward Chest functionality.

Thank you!
