fix(DB/SAI): Trident of Naz'jan to SAI (#1736)

- Remove item script for Trident of Naz'jan (Use: Impale Leviroth while he slumbers in the waters below Riplash)
- Restore Immune to PC flag on reset.
- Add missing in-combat spell.
- Change inhabittype so the NPC's corpse doesn't fall to the sea floor when he dies
