buildStatusText and buildDailyReport now use formatDateForCalendar
to convert the stored Gregorian date to the user's calendar type
(jalali/hijri/gregorian).
Previous approach (send \u200C then immediately delete it) lost the
reply keyboard because Telegram may not persist the keyboard from a
deleted message. Now we delete the OLD keyboard message and keep the
new one, ensuring the reply keyboard is always present and correct.
