Support Quest Item Synchronization and Party Member Progression

[otsffs]

1. Quest Item Synchronization: Fixed an issue where quest items were incorrectly removed from inventories. Ensured quest items are identified via IsQuestItem and properly retained and synchronized across relevant actor inventories. 2. Party Member Quest Progression Support: Implemented functionality allowing party members to accept quests by interacting with NPCs. Enabled party members to obtain quest items and use them to advance quest progress.
