[FEAT] retain settings

[Olzeke51]

Objective

retain (user) neon.yaml & ngi_user_info.yml settings when upgrading. [as happens in beta update]
this would not require the user to reload settings via voice and/ or ssh/mana
[my email address is hard for neon to translate garyz.dev1

Initial Implementation Requirements

create a partial 'settings' file on the root partition for the user settings
[only if user wants them]

Other Considerations

user should be asked to retain current settings
create a 'settings' file of some sort for the initial install of OS

This should already be preserved during updates. The home directory is restored with this method, after an update.

The backup is retained at /opt/neon/old_overlay. Is something not restoring properly? Can you check if the expected configuration is present at the backup location?
