Travelling pointing arrows, brains can no longer point (#24864)

* Decoupled from gravity, constant animation time, manual networking, cubic interpolation

* Reduced overshoot

* Implemented PointAttemptEvent, reacts with mobstate & sleeping

* Brains can no longer point, PBs must be inside a chassis

* Removed chassis check, made callback more obvious
