Refactor light range and angle calculations

Browse Source 
Updated how light range and spot angle are calculated and packed for both editor and runtime scripts, distinguishing between sphere and non-sphere lights. Adjusted shader logic to use new packing for spot light contribution, improving consistency between CPU and GPU representations.
