Fix: body keeps orientation on target loss, fix close-range selection

Browse Source 
PostureComponent: body no longer returns to original yaw when
TargetActor is cleared — only head and eyes return to neutral.

InteractionComponent: add AgentEyeLevelOffset (default 150cm) so
the view cone check targets chest height instead of feet, preventing
selection loss at close range.
