Add the D7 attendance sparkline to member detail; tighten the News list rows

Member detail: a 12-bar season attendance sparkline (present/absent/upcoming)
beside Present/Absent/No-reply totals, shown for any rostered non-guardian
member with events this season (events.services.attendance.member_attendance_
sparkline/_counts). News list: rows are one dense line (status pill inline
with the headline, everything else folded into a single meta line) instead
of the previous multi-line stacked layout that read as a small card per item.
