A finished session prints three areas with their device readings, so a course
with any history pushed the sessions that still need work off the screen.
Each session is a collapsible card now, with the scannable facts kept in the
head — number, status, date, staff, and an area count so opening is a decision
rather than a guess. History starts collapsed; a session that still needs
booking starts open, because its button is the reason it is on the page and
should not sit behind an extra click. A session with neither areas nor an
action has no body and renders as a plain row rather than an empty toggle.
