Race Updates

Added the first implementation of the Photo Finish system.
Drafting/slipstream mechanics are now more advanced and also take nearby horses on the sides into account.
The system is still being tuned: reaching 100% drafting is currently impossible by design while balancing is in progress.
The groundwork for future wind simulation has also been prepared.
Race endings are now correctly aligned with the real finish line regardless of race distance.
Code support has been added for a future “highlighted finish line” visual effect that will activate during the final lap. Planned for next week.
Integrated Martina’s new jockey animations.
Next step: sync them properly with the new horse animations and add IK support.
Started a new graphics optimization and visual improvement pass across the racing experience.
Work in progress and ongoing.
