 * Apply a role-specific OM model override to an in-memory `GlobalSettings`.

 * When switching `activeOmPackId` from a built-in pack to `'custom'` we also
 * snapshot the *other* role's currently-resolved model into its override
 * field. Without this, the other role would silently lose its model on next
 * startup because `resolveOmRoleModel` would no longer resolve it from the
 * (now-overridden) pack.
 *
 * Exported for unit testing; `persistOmRoleOverride` is the disk-backed wrapper.
