PACKAGE WL7 - DAILY LUNCH DEDUCTION FIX

Problem:
Lunch was being deducted per work session. If staff clocked out and then clocked in again on the same day, the next closed session could get another full 60 minute lunch deduction.

Correct rule:
Lunch is deducted once per staff member per day.

Example:
60 minute lunch setup.
Session 1 has 13 minutes working lunch.
Daily lunch deducted = 60 - 13 = 47 minutes.
Any later session on the same day must not deduct another 60 minutes.

After extraction:
Open Working Lunch Report again for the same date.
The second session after clock-out should not get another full hour lunch deduction.
