Potassium Mod

Reported by 7N4D6Un Issue #11.

Fixed

• Fixed misleading vendor-native upscaling availability from the GitHub log: FSR3, DLSS, and XeSS now stay pending/native-only unless their real native bridge backend is detected.
• Improved Potassium settings layout so descriptions and status text fit better on smaller or resized windows.
• Shortened settings button labels to avoid clipping.
• Added clearer upscaling runtime status, including Iris and VulkanMod compatibility pauses.
• Clarified shader cache status when Iris owns the shader pipeline instead of showing misleading empty cache counts.
