[REQUEST] Rename "migrated" store for a better onboarding

Is your feature request related to a problem? Please describe. As a new user, discovering that each installed app is suffixed with -migrated in the default mdns entry, in the app breadcrumbs, and in backups id, seems very strange, feeling as something went wrong.

Describe the solution you'd like

• Not have -migrated suffix for official apps
• AND/OR suffix only for duplicates apps
• AND/OR name the default official appstore default or official but not migrated

Describe alternatives you've considered Renaming it myself.
