Batch B (points 5-6): the detail page called every national figure a
'National avg'. All of them come from the official-DfE national-averages
marts (KS2/KS4 headlines), so they are England averages — relabel to
match the compare screen's provenance convention ('England average' for
official figures; the detail page has no computed benchmarks, so no
'state-school average (computed)' label is needed). Point 6 (anchoring
every number) is already satisfied on the detail page via DeltaChip.
