Refactor logging in IcaRecipeParser and QuickImportService to use NestJS Logger

- Updated IcaRecipeParser to replace console.log statements with Logger for better logging practices.
- Enhanced QuickImportService with Logger for consistent logging and error handling.
- Changed quantity validation in CreateRecipeIngredientDto and CreateRecipeDto to allow zero.
- Removed CanonicalNameForm and NameForm components from the frontend.
- Updated EditProductForm to use a select dropdown for categories instead of a text input.
- Added validation for product name, canonical name, and category length in product update action.
- Refactored unit options into a separate file for better reusability across components.
- Removed unused API fetching functions and inventory types to clean up the codebase.
