The header target subtracted summary.acquiredDays, which includes fractionedDays
(and bonusDays via the full-year acquired), so a full-year forfait with weekend
work or HR fractioned days showed <218. Full year = contractual 218 (capped at
period business days); entry year = businessDays − entry acquired (repos + carried
CP, excluding bonus/fractioned). Extracted computeForfaitWorkTargetDays + 3 tests.
