Refactor logging and improve image optimization in RecipeRoutes and ExifUtils

- Removed print statements for initialization and setup in RecipeRoutes to reduce console clutter and improve logging practices.
- Updated image optimization parameters in RecipeRoutes to enhance image quality by increasing the target width.
- Modified user comment handling in ExifUtils to ensure proper formatting when appending recipe metadata, improving metadata consistency.
