[3.3.5] Core/Client: Client desync on spline movement with MoveSplineFlag::Flying #16702

Client does spline movement differently from the server for movement with MoveSplineFlag::Flying. Client has a 'slow start' with acceleration towards the end, while the server seems the opposite. I'm guessing client doesn't really use catmull-rom or at least it uses different parameters (I don't know enough on the matter).

You can replicate the problem by stunning a flying creature that is moving on a relatively long path to you (single point! no pathfinding). Stun it halfway through and sometimes you'll see quite large 'blinks' forward.

In an older core when a player is doing this quest: https://woehead.way-of-elendil.fr/?quest=12856 when the drake starts the waypoint you will see it teleporting and freezing (from the point of view of a second character) but I'm not able to reproduce it in the current revision.

Should be resolved (#22582).
