Description

This PR solves two key issues with our previous 60 FPS modernization:

1. Game Speed Acceleration (Fast-Forward effect): By default, the simulation logic tick rate (30 Hz) was tied directly to the rendering FPS limit, causing the game to run at 200% speed on a 60 FPS cap. Enabling the logic time scale decouples them completely.
2. SagePatch.ini Migration: Existing configurations previously stuck to 30 FPS because their existing SagePatch.ini was not updated. We now auto-migrate existing setups by appending the 60 FPS limit defaults if they are missing.
3. Skirmish FPS slider: Redesigned the Skirmish menu options slider to control the rendering FPS cap directly (ranging from 30 FPS up to 120 FPS, with uncapped/-- limit for values over 120 FPS).

Changes

Core / Shared

• FramePacer.cpp: Enabled m_enableLogicTimeScale = TRUE by default in the constructor so logic ticks at 30 Hz regardless of the render framerate.
• GadgetSlider.h: Added GadgetSliderSetMinMax to dynamically override the slider boundaries.

Generals (Base) & Zero Hour (MD)

• GlobalData.cpp: Set the default m_framesPerSecondLimit = 60 and m_useFpsLimit = TRUE.
• GameEngine.cpp: Added an auto-migration check to read and inject 60 FPS defaults into existing SagePatch.ini setups, and updated the default template for fresh setups.
• SkirmishGameOptionsMenu.cpp: Set up the "Game Speed" slider to act as an FPS limit slider with bounds 30 to 121 (where values > 120 represent uncapped --).

Verification

• Both Zero Hour (z_generals) and base Generals (g_generals) targets successfully compiled on macos-vulkan preset.
