test: point the live milestone assertion at P5 after the backlog reconcile

Closed the 15 genuinely-shipped issues on the dogfood repo (scheduler, Monte Carlo,
calibration, lifecycle, model router, query_project, capture_work, record_directive,
etc.) so the board reflects reality: 10 open / 24 done. P2 dropped off Runway once
all its work shipped (a milestone with no open scope isn't runway — correct), so the
live spec now drills into P5 (which still has open scope) instead of P2.

No code change — this only updates the live assertion to match the reconciled backlog.
