feat: Update enemy AI and movement systems

- Enhanced Physics2D layer collision report with new interactions between Player and Enemy layers.
- Refactored BD_InvestigateLastKnown to streamline animation handling and improve readability.
- Simplified BD_MaintainCombatDistance by consolidating movement stop logic.
- Updated BD_MoveToPlayer to set AI phase on start.
- Improved BD_Patrol logic with better handling of stuck states and path failures.
- Enhanced BD_PatrolWaypoints to manage stuck conditions and retry logic more effectively.
- Refined BD_ReturnToHome to remove unnecessary animation calls.
- Updated BD_WalkRandom to ensure AI phase is set correctly on start.
- Improved EnemyAbilityBase to delegate target facing to the movement system.
- Enhanced EnemyBase with new movement methods for better control.
- Refactored EnemyMovement to introduce a new input system for handling movement and facing.
- Added EnemyMoveInput struct to encapsulate movement intentions.
- Updated Physics2DSettings to reflect new layer collision matrix.
- Introduced RTK CLI instructions for optimized command usage.
