The "until <date>" only appeared for a PAID due, because the annotation filtered
status=PAID. A WAIVED period is settled just the same — the club is covered for
that time, and its end is still when grace would start — so it belongs there too.
The annotation is now `covered_until` (furthest-out period end where status is PAID
or WAIVED) plus `covered_status`, read from the same ordered row so the table can
badge "paid" vs "waived" and still show the date for both. Rides the same single
query — assertNumQueries(1) still holds.
Full matrix now: no plan -> n/a; paid -> "paid, until X"; waived -> "waived, until
X"; unpaid/partial -> the amount owed (no date); a paid-then-owing club shows the
amount, not the stale cover date. A subscribed club with no covering period at all
(only cancelled dues) shows a dash rather than a bare "paid".
