Refactor and enhance UI, localization, and file name handling

- Refactored file handling: added backup directories, improved mafile naming strategy, and introduced renaming functionality.
- Enhanced UI: updated `MainWindow`, `SettingsView`, and dialogs with new controls, commands, and improved layouts.
- Introduced `TextFieldDialog` for user input with localization support.
- Improved localization: added new strings for buttons, errors, and tooltips. Removed all user-observed not localized strings
- Fixed clipboard handling logic in `ClipboardHelper`.
- Added 'Create Group' button in mafile's context menu and corresponding dialog view
- Implemented `RequiresAdminAccess` check before updating program and requesting previlegies
