j.foucher 2e04cb0334 Fix perception, patrol, and spline following for PS_AI_Behavior ...

Perception:
- Configure senses in BeginPlay + RequestStimuliListenerUpdate (not constructor)
- Filter threats by team attitude: only Hostile actors generate threat
- Skip Friendly and Neutral actors in CalculateThreatLevel and GetHighestThreatActor
- All Hostile actors are valid threats regardless of TargetPriority list

Blackboard:
- Use SetValueAsEnum/GetValueAsEnum for BehaviorState key (was Int)

Patrol:
- Auto NavMesh patrol when no manual waypoints defined
- Project HomeLocation onto NavMesh before searching random points
- Fallback to NPC current position if HomeLocation not on NavMesh

Spline following:
- Choose direction based on NPC forward vector vs spline tangent (not longest distance)
- Skip re-search if already following a spline (prevent BT re-boucle)
- Reverse at end: wait for NPC to catch up before inverting direction
- Use NPC actual CharacterMovement speed for target point advancement
- Face toward target point (not spline tangent) to prevent crab-walking in turns
- Junction switching: direction continuity check, 70% switch chance, world gap tolerance
- Debug draw: green sphere (target), yellow line (gap), cyan arrow (tangent), text overlay
- Add GetWorldDirectionAtDistance to SplinePath

Editor:
- Add Placeable to SplinePath and CoverPoint UCLASS
- Add PersonalityProfileFactory for Data Asset creation
- Add EnsureBlackboardAsset declaration
