Previously any past workday without a closed_days record blocked week
close. Now only days that actually have entries require an explicit
close. Empty workdays count as 0h worked, which is reflected in the
weekly delta automatically.
- WeekService.CloseWeek: after finding no closed_days record, check
whether the day has any entries; only error if it does
- NewWeekService: takes EntryStore to support the above check
- Updated TestCloseWeekMissingDayFails to reflect the new semantic
(test now creates entries on Friday but leaves it unclosed)
