Give each user message its own copy, reply and time

Two prompts sent close together (as while a bot is still answering)
shared one row under their group: every copy button bunched beside the
last message's time. Each user message now has its own row, with its
copy button, a new Reply button (once it is saved) and its own time.
copyableMessages is gone with the shared row.
