Refactor panel position management and enhance recipe card handling

- Removed redundant updatePanelPositions calls from various components and centralized the logic in the uiHelpers.js for better maintainability.
- Introduced appendRecipeCards function in RecipeManager to streamline the addition of recipe cards from search results.
- Cleaned up unused code related to search input handling and recipe loading, improving overall code clarity and performance.
- Updated HeaderManager and SearchManager to utilize the new updatePanelPositions function, ensuring consistent panel positioning across the application.
