Custom UI Scale Slider in Video Settings

Currently, the UI scale option in video settings only offers fixed presets (such as 100%, 167%, etc.). I propose replacing or enhancing this with a continuous UI scale slider that lets players fine-tune their interface size between a minimum and maximum limit. Allows precise interface scaling for non-standard screen sizes, tablets, and monitors. Improves HUD accessibility and customization beyond rigid default steps. Helps players fit elements like hotbars and inventories comfortably on any display resolution.
