Project · a roadmap bar's end and a workload bar's cap, tested

A roadmap bar ran through its last day, but no test looked at its end:
a bar stopping at the last day's start stayed green. The roadmap test
now asserts October's bar reaches the span's end. The workload bar's
share, capped at the whole track, moves into Load::filled with a unit
test, so a load past capacity cannot draw past its track unseen.
