Magiclysm NPC mission dialogue fix

NPC were assigned TALK_MISSION_OFFER instead of TALK_MISSION_LIST, and while it works for accepting their jobs, it doesn't provide necessary function for them to say that they don't have any more jobs for the player, resulting in `assign_mission: mission_selected == nullptr`

Except for old magus, who has necessary checks, but I've changed them too in case of future updates with more quests added.
