Fix IsCoverNeeded decorator: resolve AimTargetActor to owning Pawn

Browse Source 
- IsCoverNeeded used Cast<APawn> on ThreatActor which failed for AimTargetActors
  → always returned true (assume dangerous) → enemies took cover against civilians
- Fix: use FindOwningPawn to walk Owner/Instigator chain to the actual Pawn
- Revert inline civilian check in EvaluateReaction (decorator handles it in BT)
