Fix enum mismatch: Update Python enums and seed data to match database uppercase values

- Fixed ProductType enum values from lowercase to uppercase (INGREDIENT, FINISHED_PRODUCT)
- Fixed UnitOfMeasure enum values from lowercase/abbreviated to uppercase (KILOGRAMS, LITERS, etc.)
- Fixed IngredientCategory enum values from lowercase to uppercase (FLOUR, YEAST, etc.)
- Fixed ProductCategory enum values from lowercase to uppercase (BREAD, CROISSANTS, etc.)
- Updated seed data files to use correct uppercase enum values
- Fixed hardcoded enum references throughout the codebase
- This resolves the InvalidTextRepresentationError when inserting inventory data
