refactor(import): Implement DownloadManager, FolderBrowser, ImageProcessor, and RecipeDataManager for enhanced recipe import functionality
- Added DownloadManager to handle saving recipes and downloading missing LoRAs. - Introduced FolderBrowser for selecting LoRA root directories and managing folder navigation. - Created ImageProcessor for handling image uploads and URL inputs for recipe analysis. - Developed RecipeDataManager to manage recipe details, including metadata and LoRA information. - Implemented ImportStepManager to control the flow of the import process and manage UI steps. - Added utility function for formatting file sizes for better user experience.
