Item Bonuses Not Applied During Combat

Issue Summary:
Item bonuses such as flat bonuses, override bonuses, and modifier bonuses are properly displayed on the character stat screen. However, these bonuses are not reflected during combat or encounter scenes.

Steps to Reproduce:

1. Equip a character with items that grant stat bonuses (e.g., weapon with +10 Max HP, armor with +10 AC).

2. Observe that the character sheet updates correctly (e.g., HP becomes 38/38, AC becomes 22).

3. Enter a combat or encounter scene.

4. The combat stats revert to the base values (e.g., HP shows 28/28, AC is 12), and the item bonuses are not applied.

Expected Behavior:
The combat system should reflect the total character stats, including all equipped item bonuses.

Actual Behavior:
Combat scenes ignore bonuses from equipped items. Stats revert to base values:

• Max HP bonus from weapon is not applied

• AC bonus from armor is not applied

• Character appears weaker than intended during combat

Impact:
This issue significantly affects game balance and progression, as characters do not benefit from equipped gear in actual combat scenarios.
