fix(panel): the build page trusts the server-side owner tier and drops its mock build seeds

  const locale = i18n.language;

  const now = Date.now();

  const config = useConfig();

  const { identity } = useTier();

  // The owner tier comes from the server-side /me verdict (TierProvider), never

  // from guessing at the address: the old mock-era email heuristic misread the

  // real owner ([email protected]) as non-owner while treating any

  // "owner@…" address as one.

  const { isOwner } = useTier();

  // Form & Dialog State

  const [dialogOpen, setDialogOpen] = useState(false);

  const [loadingSubmissions, setLoadingSubmissions] = useState(false);

  const [selectedSub, setSelectedSub] = useState<Submission | null>(null);

  const isOwner = useMemo(() => {

    if (!identity?.email) return false;

    const emailLower = identity.email.toLowerCase();

    return emailLower === "[email protected]" || emailLower.startsWith("owner@");

  }, [identity]);

  const visibleSubmissions = useMemo(() => {

    if (isOwner) {

      return submissions;

      const stored = localStorage.getItem(LOCAL_STORAGE_KEY);

      if (stored) {

        setBuildIds(JSON.parse(stored));

      } else {

        // Seed default IDs so mock builds are loaded on first visit.

        // In production, querying these will 404 and safely show the empty state.

        const defaultIds = ["bld-1", "bld-2"];

        localStorage.setItem(LOCAL_STORAGE_KEY, JSON.stringify(defaultIds));

        setBuildIds(defaultIds);

      }

    } catch {

      setLoadingBuilds(false);
