Fleet Ops integration status no longer depends only on a config
boolean or the most recent outbox event: N8nIntegrationStatus now
reports per-canonical-workflow evidence (last successful outbox
delivery for the return workflow, latest service-triggered
data_quality_scan_run for the scan workflow, latest
n8n_workflow_failure_registered for the error handler, and "not built"
for the still-blocked RAGcore sync), plus an error-handler summary
(total failures registered, latest failure + which workflow).
Automation page renders this as a localized workflow table (EN/NL/FR)
with technical workflow names tucked under a "Technical details"
disclosure, matching the existing progressive-disclosure pattern.
