Add carapace animation and handle hive_link ATK buff restoration

- Implement `_animateCarapace` handler in the event switch to support the new carapace effect.
- Update `_restoreBuffsForDisplay` to temporarily undo `hive_link` ATK gains, ensuring pre-battle animations display the correct pre-buff values.
- Update `_reapplyBuffs` to re-apply `hive_link` ATK gains after state rendering, ensuring the data model is correct for subsequent animations like `animateBerserkGain`.
- Update comments to reflect that `hive_link` is now included in the list of buffs temporarily undone for display purposes.
