Give the analytics overview a per-parent, per-year balance series

Each parent projection now carries one entry per calendar year from
birth to the fourth birthday: vacation earned, carried in, planned,
left, carried out and expiring under Semesterlagen's 20-day floor and
5-year carry-over, plus parental-leave days used and left at year end
with the age-4 clamp applied in the birthday year. The overview sums
them into per-year totals. Frontend types, mapper and fixtures follow.
