Issue/Bug description: Add an option in Cosmic Settings to create a backup .dotfile that includes all system settings, making it easy for users to back up and restore their configurations. This feature should encompass the following categories:

• Desktop -> save (panel , dock, window mgmt & workspace)
• Power & Battery -> save (power mode & saving options)
• Input Devices -> save (special char entry & keyboard shortcuts)
• Time & Language -> save (timezone & date-time format)
• Installed Apps -> save (apps in respective format .deb or flatpak)

Expected Behavior:

• The .dotfile should store all user-defined settings from the mentioned categories, including manual configurations.
• Exclude appearance and wallpaper settings to keep the focus on functional configurations. Restore Functionality
• Users should be able to restore their settings by simply loading the .dotfile via the Backup & Restore section.

Use Case:

• Facilitates quick recovery or migration of settings when reinstalling or moving to a new system.
• Install all necessary apps in one go
• Simplifies managing complex configurations for power users.
