Scope versement reste-à-verser to its own compte(s), not the entrée total

versementStatus() was reusing reconciliationByEntree()'s aggregate
resteAVerser/surVerse, which sums residuals across every compte the
entrée touches -- including comptes tied to *other* sorties linked to
the same entrée. A versement paid entirely through Maud could show
"reste à verser" driven by an unrelated Sandrine/Chloé shortfall on
the same entrée, or vice versa mask its own compte's sur-versement
behind an unrelated compte's surplus.

reconciliationByEntree() now also keeps a per-compte residual map
(parCompteResidual), and versementStatus() sums only the residuals for
the compte(s) this specific versement's own répartition touches.

Verified against a real case: entrée EPAU F2549-50-51 (répartition
across 8 comptes) with one linked "Versement Maud" of -10 000€ against
an entrée-side Maud share of 5 632,86€. The entrée's own badge still
correctly shows the aggregate ("reste 24 325,54 € · sur-versé
4 367,14 €"), but the versement row itself now shows "Sur-versé :
4 367,14 €" -- its actual Maud-only residual -- instead of the
previous "Reste à verser", which was purely an artifact of the other
7 comptes' unrelated shortfalls.
