Refactor game items and rename 'ChipsSticks' to 'RawChips'

This commit includes a significant refactoring of the game items. The 'ChipsSticks' item has been renamed to 'RawChips' for clarity and accuracy across several game content files. Additionally, the 'FriedChips' and 'FriedFish' items have been reclassified from 'Ingredient' to 'Meal'. This change streamlines the hierarchy and makes the game items more intuitive to understand and use.
