fix: address reviewer feedback — null config, auto-expand, dedup helper

P1: enabled_model_count crashed with AttributeError when a model in
    model_configs had a null/non-dict value. Added isinstance(m_cfg,
    dict) guard before calling .get().

P2: FAILURE rows no longer auto-expanded after the earlier "collapse
    by default" change. Restored auto-expand for FAILURE rows only,
    keyed on backUpData (fresh loads) so filter changes don't reset
    user-expanded rows.

P2: Replaced the local formatRelativeTime in no-code-model.jsx with
    the shared getRelativeTime from common/helpers.js which already
    handles both past and future dates.
