bugfix(gameengine): Prevent logic time accumulation while the game is halted

[bobtista]

• Fixes Game logic fast-forwards at render rate after unpausing when the logic time scale is active #2864
• Follow up for bugfix(logic): Restore retail compatibility after change to frozen time check #2803

Since #2803 the update no longer passes FramePacer::IgnoreHaltedGame, so getActualLogicTimeScaleFps returns 0 while the game is paused. That makes targetFrameTime infinite, and m_logicTimeAccumulator banks the entire pause duration, which then drains at render rate after unpausing — the game runs at 2x for about as long as it was paused.

Now returns early when the logic time scale fps is 0, leaving the accumulator untouched while the game is halted, so the game resumes at normal speed.

Todo:

• Test pause/unpause with render fps 60 and logic time scale 30
• Replicate to Generals

Greptile Summary

This PR stops halted game time from being banked by the logic pacer.

• Adds a zero-or-negative logic FPS guard in the Generals update path.
• Applies the same guard in the Generals Zero Hour update path.
• Leaves the logic accumulator unchanged while the game is paused or halted.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The new guard matches the halted-game path where effective logic FPS becomes zero.
• The mirrored files keep the Generals and Zero Hour behavior aligned.

Important Files Changed

Filename	Overview
Generals/Code/GameEngine/Source/Common/GameEngine.cpp	Adds an early return before accumulator math when the effective logic FPS is zero or negative.
GeneralsMD/Code/GameEngine/Source/Common/GameEngine.cpp	Mirrors the halted-game logic FPS guard in the Zero Hour game-engine update path.

It also broke pause on mismatch partially, because fast forward overrides pause now.

[Caball009]

This should go after

const Int logicTimeScaleFps = TheFramePacer->getActualLogicTimeScaleFps(logicTimeQueryFlags);

otherwise this function returns true when replay mode is enabled & the game is paused & fast forward is enabled.

It doesn't need a comment as far as I'm concerned, because it's our own function and straightforward what it does and why it does it.
