Review follow-ups: (1) createFromFormat('Y-m-d') keeps the current time, so a raw
DateTime comparison wrongly excluded an employee ending on the from-day (and dropped
first-day absences); normalize from/to to day bounds and compare contract periods on
date only (Y-m-d), mirroring the calendar view. (2) eager-load contractPeriods in
findForPrintBySiteIds to avoid an N+1 during filtering. Added a boundary test.

The calendar view hides employees whose contract doesn't intersect the displayed
month, but the absence PDF print still listed them. Apply the same intersection
filter (hasContractInRange over [from, to]) in AbsencePrintProvider, and reject
invalid from/to dates. A employee who left in April no longer appears on a May print.
