The completed flag lived only in app-group UserDefaults
(UserDefaults(suiteName: appGroupSuite)). On free SideStore accounts the
app-group container isn't provisioned, so the suite read as nil: save was a
silent no-op and load always returned false -> onboarding re-appeared on
every launch even after finishing and granting all permissions.
Switch to saveString/loadString (keychain-first, app-group mirror) under
onboardingCompletedKey, matching favourites/distance-unit persistence which
survives reinstall and works without a provisioning group. loadString falls
back to the app-group mirror, so anyone who previously completed on a
provisioned group keeps their flag; users on unprovisioned groups complete
once more and then it sticks.
