fix bugs & add new dialogs

- Introduced `CredDialog` to prompt users for access to secure backends (Windows Credential Manager or Secret Service).
- Integrated `CredDialog` into `AppsWidget` initialization flow, allowing users to skip signing in.
- Updated `SettingsManager` to manage user preferences for showing the keychain dialog.
- Enhanced `DevDiskManager` and related classes to utilize a new method for creating device disk image paths.
- Refactored `VirtualLocation` to support saving and displaying recent locations.
- Improved UI responsiveness and layout adjustments across various widgets.
- Cleaned up unused code and comments for better maintainability.
