fix: move collision_delay after step_recovery to prevent deadlock

collision_delay was placed before the walk_speed/step_recovery block,
causing step_recovery to never tick when collision_delay was active —
entities stayed permanently pre-empted at path_index=0.

Correct order: step_recovery (must tick every frame) before
collision_delay (only checked when entity is ready to move).
