Color and bold Montant HT to distinguish entrées from sorties

Single anchor per row -- Montant TTC and the 8 compte columns stay
neutral, so the table doesn't turn into a red/green garland. No 0.5€
threshold like soldeClass (used for aggregate totals): individual
lines are often small (a -1.07€ OVH renewal shouldn't read as
"neutral"), any nonzero sign gets colored.
