Core/GameObjects: Skip LoS checks for traps (#23936)

* Core/GameObjects: Skip LoS checks for traps

* Core/GameObjects: Fix spells cast by traps missing always

* Scripts/Spells: Fix WSG heal buff not healing

The WSG green heal buff is now cast by a GameObject so the spell target should be used to calculate the healing, not the GameObject.

(cherry picked from commit 909941e1b44250b0fa646d363af817f40ca48355)
