[NOTICKET] fix(scope): lookup artefacts and typed site ids (P0-4)

- only a `${tN.col}` value handoff marks tN as a lookup; a Pattern-A
`${t2}` data feed made the answering query a "lookup", so the line fell back
to the site lookup and read "(sebagian kueri)".
- _strip_broken_id_filters strips both FK ends: a typed
`vw_dim_site.site_id = 2009` (Check 8j rejected it, costing a retry).
- the scope line no longer prints `site_id 2009` next to `site_code IPR`.
