fix(xtream): never report another panel's status for the selected playlist

Review follow-up (Greptile): callers gate content initialization on the
value `checkPortalStatus()` returns for whatever is selected NOW. When the
answer no longer describes the selected playlist (source switch or in-place
edit during the request), the store's own verdict about the current
selection is returned instead of the old panel's status — on success and on
failure alike.
