'Matcha manuellt' as designed: outside rows on the left (multi-select),
verifikat without an outside row on the right (single-select), the
selection's arithmetic in the footer, and one Koppla that is enabled only
when the difference is 0. Mode lives in the URL (?mode=match).
Engine: a pair is now one OR MANY outside rows against one verifikat.
Bank groups link per transaction (manualLink allows N:1 by design, so
partial success is reported per row). Skattekonto groups go through the
new linkSkattekontoRows: the verifikat's 1630 side must settle the sum,
one guarded UPDATE links the whole group, and a partial hit is rolled
back as LINK_RACE. 1:M stays UNSUPPORTED_PAIR_SHAPE until the residual
link table (6c). v1 pitfalls + API skill regenerated.
