The Demand Calculator used max(now, start) as the effective planner start,
which caused asymmetric counting when the current time fell between morning
and evening doses. For example, at 15:00 a medication with 07:00+20:00
intakes over 3 days showed 5 pills (2+3) instead of 6 (3+3) because the
morning dose on the start day was skipped while the evening was counted.
Changes:
- Use the user-selected start date directly instead of max(now, start)
- Optimize calculateUsageInRange to skip ahead to the relevant range
instead of iterating from the original blister start date
- Add regression tests for asymmetric counting and blister-before-range
