fix: restart the stalled autonomy pipeline and make calibration honest

Archive ingestion had been dead since 2026-08-02 because nothing in the
compose stack actually ran it. Everything downstream starved from there.

- add ingest + enrichment services. server.js only starts the scheduler when
  DURIIN_RUN_SCHEDULER is not "false", and workers/index.js was not running at
  all, so articles never got event_id/content/has_embedding and the coordinator
  had nothing to lease.
- pass an explicit origin from coordinatorWorker. it was never passed, so
  acceptProposal defaulted to 'live' and 464 historical backfill predictions
  were recorded as live. that also meant verifyEvidence got a null cutoff and
  skipped its date check entirely.
- coarsen cohortKey to event families + horizon buckets. 201 free text event
  types produced 221 cohorts averaging 2.76 samples, so the n>=30 gate could
  never be reached and everything abstained for the wrong reason.
- gate on cohort diversity, not just sample count. one ticker was roughly half
  of all resolved outcomes, so a pure count gate was measuring one company.
  unknown diversity abstains rather than passing.
- resolve the admin archive db explicitly and probe it. it relied on a
  Dockerfile symlink, and without it better-sqlite3 quietly creates an empty
  file and serves a phantom archive.
- clamp implausible future publication dates at ingest.
- pin the db backend to sqlite by default. compose hardcoded postgres "true",
  which would have overridden the operator's own .env on the next redeploy and
  pointed everything at a stale snapshot.

scripts/repair-autonomy-labels.js relabels the affected rows. it is dry run by
default and has not been applied.
