No-show rescue

An empty chair costs a clinic the same as a busy one, and most no-shows are people who simply went quiet after asking about a slot.

This template chases the gap between interest and attendance. Anyone who asked about an appointment and stopped replying gets one follow-up that names the treatment they were asking about and offers to confirm; anyone who wants to move their visit can do it in the chat instead of phoning. Nobody is nudged twice, and a person asking to cancel outright goes to the team rather than into a loop.
