* fix(bookkeeping): reverse-charge VAT in booking templates is 25% of the base, not 20%
applyTemplate() extracted VAT out of the total (rate/(1+rate)) for every
vat line, including the fiktiv-moms pair of reverse-charge templates.
Under omvand skattskyldighet the supplier charges no VAT, so the total IS
the beskattningsunderlag: on 807.99 kr the seeded EU-purchase template
booked 161.60 kr (20%) on 2614/2645 instead of 202.00 kr (25%),
understating Ruta 30-32 and Ruta 48 on the momsdeklaration.
Fiktiv-moms lines (2614/2624/2634 output, 2615/2625/2635 import,
2645/2647 input) now compute amount x rate on top of the base.
deriveTemplateLinesFromBooking ("Spara som mall") gets the mirror fix:
RC legs no longer inflate the derived total (they net to zero), and RC
rates snap against the base, so a correct RC booking round-trips.
Counterparty/SIE learned patterns already strip RC legs and regenerate
them via generateReverseChargeLines with the gross base; those paths
were correct and are unchanged.
User-reported: "Er automatiska utrakning ar pa 20%, inte 25%".
