Mid-week hire weeks (e.g. CDD starting Thursday) had their first day with no
contract, so the week was classified CUSTOM and the 25%/50% overtime bonuses
were disabled. Anchor the week's contract type/nature on the first contracted
day instead, so a 35h/39h hire week keeps its overtime tiers.
Dylan CHABOISSON week 12: 7h → 8h45 (7h × 1.25).

computeWeeklyOvertime25StartMinutes used a ternary that fell back to 35h
when a day had no active contract. Once periodFrom was uncapped (so the
RTT week iterates the full exercise), pre-hire days were silently
contributing 7h each to the weekly threshold, erasing the 25% overtime
for the employee's first partial week.
Dylan CHABOISSON week 12 (Mar 19 hire, worked Thu 9h + Fri 9h30 +
Sat 3h30 = 22h): threshold was 36h (incorrect), now back to 15h (Thu 8h
+ Fri 7h) so the 7h above threshold + 1h45 bonus are correctly credited.
