Technical fixes and optimization of game mechanics

🌟 Fixes

⚪ Skill casting is now disabled while transitioning into a trade.
⚪ Fixed an issue where casting could be interrupted during invulnerability (e.g., under the Enchanter Ability – Barrier buff).
⚪ Resolved a problem where the system message for item pickup in a party was sometimes not displayed.
🟡 Important: Fixed an error in calculating maximum HP/CP/MP under buffs. With a maximum HP boost, the value could decrease by up to −2500 HP.

🔧 Additional Changes

⚪ The minimum number of participants required to start the Olympiad in cross-class competitions has been reduced to 4.
⚪ In Community Board → Buffer → Mage, the buff set now includes Acumen and Concentration.
⚪ Reduced the strength of mobs in Mid Farm.
