Turn the console landing page into an operational dashboard.
- new internal/opsstatus: read-only Postgres projection via go-jet — ping +
per-status COUNT/GROUP BY on runtime_records, mail_deliveries,
notification_routes, and a malformed-intent count; degrades per-probe into
Snapshot.Errors rather than failing the page
- dashboard renders backend readiness, database health, the three status
tables, the malformed count, and any collection errors; falls back to a
"monitoring not wired" note when no reader is injected
- AdminConsoleHandlers now takes an AdminConsoleDeps struct (Monitor + Ready
added) so later stages add service refs without churning the signature
Tests: opsstatus store test against a Postgres testcontainer (empty schema +
one enqueued delivery); dashboard render tests with a fake reader (with and
without monitoring).
Docs: ARCHITECTURE 14.1 + FUNCTIONAL 10.2.1 (+ru) describe the dashboard.
(Prometheus /metrics exporters were already enabled in dev-deploy in Stage 1.)
