feat(cockpit): expose first_pass_yield and a real escaped-defects metric (#709)

The Company Scorecard renders three charter objectives but the cockpit
summary only ever carried one of the metrics, so two cards read "No data
yet" permanently.

first_pass_yield is a pass-through — MetricsService.get_org_scorecard()
already computes it on the same 30d/org scope the rest of the delivery block
uses, and CockpitService.summary simply never forwarded it.

escaped_defects is new. The obvious definition — a blocker finding opened on
a task that already reached a terminal state — is unimplementable: every
producer of a task_review_findings row fires as part of a bounce whose
transition requires a non-terminal task, so it would read zero forever, and a
permanently-green card is the same fabrication the panel change removes.

What it counts instead: a blocker still at 'addressed', never 'verified', on
a task that has since completed. That is reachable because
stamp_addressed_verified only bulk-verifies rows matching its OWN origin, so
a blocker raised by one origin and never re-confirmed by that origin survives
to completion on the developer's word alone.

docs/map/metrics-observability.md documents what a zero actually means: the
one reachable trigger is a PM-origin blocker on a task escalated to the CEO
rather than completed by the PM, since escalate_to_ceo carries no
findings-resolved precondition and ceo_approve verifies only ceo-origin rows.
It also records that the count is per-finding over a rolling 30-day window,
which is not the same unit as the charter's "per release".
