PDF export: daily P&L charts match the dashboard

The daily P&L and weekday P&L charts inside exported PDF statements now line up with the same widgets on your dashboard. Previously, the PDF could bucket trades on a different day than the calendar and weekday charts you were looking at, which made side-by-side checks confusing.

After this fix, the bars in your PDF reflect the same entry-date grouping as the live dashboard, so you can share or archive a statement knowing the chart snapshots match what was on screen.
