Unify enrichment tracking and outcome-based status

Make common_tracker_patterns and common_third_parties share one
enrichment-tracking model and fix the misleading proboctl status.

Both tables now carry the enrichment JSONB provenance payload, an
enrichment_attempts counter, and a last_enrichment_attempt_at clock.
On common_tracker_patterns the enriched_at done-flag is renamed to
last_enrichment_attempt_at and stamped at claim time, so it is truthful
to "attempt" rather than "success". A row is considered to have been
through the workflow when it carries an enrichment payload, not when a
timestamp is set, which lets stale recovery key off the payload being
absent with budget remaining, exactly like common_third_parties.

The claim path reads the attempt counter and timestamp back via
RETURNING so the in-memory receiver matches the database clock instead
of a separate app-side time.Now.

The enricher builds a per-field provenance payload (description and
third-party outcomes plus the mapping attribution) and persists it via
UpdateEnrichment, named to mirror the common-third-party sibling. The
common pattern enrichment worker gains a max-attempts ceiling so a
permanently failing row stops looping.

proboctl now shows "enriched" only when every field the last run
recorded an outcome for resolved a value, otherwise "partial (X/Y)",
replacing the misleading "enriched (no description)" label.
