Dathomir Battle POI Improvements

In the SMC and NS Battle POI on Dathomir, the first row of SMC NPCs are not attackable. I kindly propose (1) making those SMC NPCs attackable just like normal NPCs and (2) replacing the SMC leader arch witch with a SMC councilwoman NPC.

The current state is nonsensical. All NS NPCs are attackable, including those in the first row on their side, but not SMC. Making the first row attackable (1) makes the factions in the battle POI balanced, (2) ensures equal loot and PVE opportunity for players, and (3) makes it easier to complete certain Witches of Dathomir kill missions. Also, the NS side has a NS elder boss. But the SMC side lacks a boss, the arch witch is not a boss NPC -- should replace it with a SMC councilwoman for balancing and PVE opportunity.

To fix a possible bug in the game that I believe has been there since live.
