No more AI for groceries items + posters under design by human artist

Hello players, i'm happy to announce i'm close to be done by replacing all AI Assets Art by human art only. i've replaced all remaining AI items and only the posters remains as i'm working with a freelance artist to design new ones. About audio, the optional jingles remain AI but if someone would like to be the voice of the game and is professional, please reach to me !

i've also fixed some minors bugs with sushi placement in hand.
