Implemented functionality to handle single file drag-and-drop in the UI, including error handling for multiple files and directories. Updated localization files to support new messages related to drag-and-drop usage and errors.
Introduced `DirectoryForSaving` for managing directory paths persistently. Integrated the new setting into relevant modules, ensuring the selected directory is saved and loaded across sessions.
This commit removes outdated dependencies and adds updated versions of required modules in the `go.sum` file. The changes ensure the project uses the latest compatible releases, improving stability and maintaining compatibility with current updates.
