fix(admissions): flag-off pages must not speak for the council
The secondary admissions section words the absence of a cut-off distance:
"<LA> has not published a cut-off distance for this school." That sentence
is true when the authority publishes nothing. It is false when the
authority does publish and the admission_distance flag is simply off — and
off is the current state, so every secondary page with an EES admissions
row has been making a claim about a council on our behalf.

The backend already draws the distinction the copy needs. /api/schools/{urn}
omits the admission_distance key entirely while the flag is dark rather than
sending null, precisely so that "we are not publishing cut-offs" stays
distinguishable from "this school has no cut-off"; lib/types.ts says so in
as many words. The page then collapsed the two with `?? null` before the
section ever saw them.

So stop collapsing it: thread the raw field to SecondarySchoolSections and
word the absence only when the feature is on. Null still gets the sentence
naming the authority — that case is unchanged and still tested.

Primary pages are unaffected: AdmissionsSection carries no absence copy and
renders nothing when there is no figure. DistanceSection already treated
absent and null alike; only its type widens.

/**
* DistanceSection — "How far away are you?"
*
* The section exists to answer one question a parent cannot answer from a
* number alone: whether their own address falls inside it. The figure itself is
* already on the Admissions tile above; this turns it into something they can
* act on.
*
* Scope note. This used to carry the full published record — chart, year table
* and a set of shrinking rings. Earlier years are now held back as a paid
* feature and no longer leave the API at all, so what remains is the latest
* year and the check against it. The pipeline is unchanged: every published
* year is still loaded into fact_admission_distance, so restoring history for
* entitled callers is a serving change rather than a re-collection.
*
* Server component; the map and postcode form carry their own client boundary.
