feat(extra-info): add more ItemMetadata states

This CL also adds logic to show the state codename if the localized
friendly name is not available. This is needed because we don't know
what the AUTOMATED_ABUSE_MANUAL_REVIEW state corresponds to, so we can't
have a friendly name and would like to display the codename instead.
