withinSlaPercent was "answered within sla_seconds / answered", so a queue where a caller timed out still showed 100%. It is now the usual service level: answered within sla_seconds out of every caller the queue is done with, leaving out those who hung up before sla_seconds (nobody could have answered them in time). Timed out and turned away count as missed; callers still waiting aren't counted. Written into 04; the page label says "Callers answered within N s". Real calls: m8-t1 now shows 50% (1 answered in time, 1 timed out, the early hang-up left out) and the milestone check 67% (2 of 3), and asserts it. The check moves to queue 552 (*45552) so it doesn't clash with m8-t1's 550 on a shared database. Task: M8-T1
