Fix animations progress & sync

[FileEX]

Summary

• Time synchronization refactor for animations (server-authoritative clock)
• Replaced unreliable GetTimestamp() / GetTickCount64_ usage with a monotonic steady_clock-based tick system.
• Fixed a bug where the server was sending elapsedTime while the client treated it as startTime.
• setPedAnimationProgress now runs in the "same" frame as setPedAnimation (setPedAnimationProgress() does not work when called in the same frame as setPedAnimation() #1172).
• When setPedAnimationProgress is set to 0 on the server, it refreshes the animation startTime.
• On the server side, setPedAnimationProgress updates the animation startTime, ensuring all clients play the animation from the same progress point.

Motivation

Fixes #1172

Test plan

crun ped = createPed(50, getElementPosition(me))
crun setPedAnimation(ped, "ped", "ko_shot_face", -1, false, false, false, true) setPedAnimationProgress(ped, "ko_shot_face", 0.5)
