Refactor backend to normalized ingredients/steps schema, remove tag color, update types/routes/services/tests. Blocking TS build error: all SQL params must be string|null; remaining bug is undefined may leak in RecipeRepository ingredient/step creation. See code for status. In-progress commit to checkpoint work.
