feat: Add Lora recipes retrieval and filtering functionality

- Implemented a new API endpoint to fetch recipes associated with a specific Lora by its hash.
- Enhanced the recipe scanning logic to support filtering by Lora hash and bypassing other filters.
- Added a new method to retrieve a recipe by its ID with formatted metadata.
- Created a new RecipeTab component to display recipes in the Lora modal.
- Introduced session storage utilities for managing custom filter states.
- Updated the UI to include a custom filter indicator and loading/error states for recipes.
- Refactored existing recipe management logic to accommodate new features and improve maintainability.
