Expand a product's additives into a risk breakdown API

Looks up a product by barcode, then JOINs every additive E-number on its label against the Open Food Facts additives taxonomy to produce a per-additive breakdown (name, class, EFSA/ANSES flags, vegan/palm-oil) AND a DERIVED overall additive-risk tier + the list of flagged additives. The MORE: turns an opaque list of E-numbers into an explained, scored safety summary in one call. Answers 'what additives are in this barcode', 'explain the E-numbers on this product', 'how risky are this food's additives', 'does this product contain concerning additives'.
