Every email shows every day of a course

A customer on a course that runs over more than one day now sees every day in every email we send them, not just the first.

Reminders, payment requests and waiver links — each day of the course is listed with its own time and boat, so nobody has to ask whether it is two days.
Short dates — subject lines and texts show the whole span, like Mon 16 – Tue 17 Nov · 2 days.
Single-day trips — look exactly as before.
