fix: resolve nested download paths for covers and lyrics (#219)

This commit fixes an issue where cover art and lyrics files were being saved in deeply nested directories (e.g. Album/Artist/Album/file) instead of the correct Artist/Album/file path. It adds an isAlbum flag to the frontend hooks to prevent redundant path construction when downloading in an album context.
