feat: add image handling to recipes

- Implemented image downloading and optimization in QuickImportService.
- Added imageUrl field to CreateRecipeDto for recipe creation.
- Created an endpoint in RecipesController to update recipe images.
- Enhanced RecipesService to handle image URL updates and optimizations.
- Updated Docker Compose to mount a volume for recipe images.
- Refactored frontend to display images in recipe grids and detail views.
- Added a new utility function for downloading and optimizing images.
- Created a new API route for handling image uploads.
- Introduced RecipeGrid component for better recipe display.
- Updated RecipeDetailClient to manage image updates and display.
- Added migration for new imageUrl column in the Recipe table.
