feat: The Lost Brother Quest

[CarlosE-Dev]

Description

Implementation of the quest "The Lost Brother".
It's a small quest initiated with the NPC Tarun, with one of the rewards being able to negotiate with the NPC. So, this part was also modified so that the negotiation can only be done once this quest is complete.

This quest is also necessary for the start of the "Within the Tides Quest" (access to Marapur).

Tested INGAME in different ways and with different characters, everything seems to work well.
