Fair PYTD comparison for current week/month

Weekly: cap pyToStr at elapsed days (not full Mon-Sun), and filter
py_sales to past days only — both give WTD vs WTD. Labels show
'PY WTD' for current week, 'PY' for complete past weeks.

Monthly: pyToStr already capped at same day-of-month; salesTo already
capped at today. Labels now show 'PY MTD' for current month, 'PY' for
complete past months.
