Subject: [PATCH] fix: use per-day-of-week colors in PDF export
 (weekday/sat/sun)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The PDF was showing all day headers in the same weekdayColor. The webapp
uses three separate color settings: weekdayColor (Mon–Fri), weekendColorSat,
and weekendColorSun. Fetch both weekend colors from DB and apply via
dayColor() helper based on d.getDay().
