Subject: [PATCH] fix: migrate language from legacy profile-scoped key to
 global key

On first launch after upgrading, if the new global key is empty,
fall back to the legacy profile-scoped key from the previous
version. Once found, the value is saved to the global key so
future reads avoid the legacy path.
