Get tenant enrichment status

Returns a tenant's enrichment progress across the record-level enrichments (translation, sentiment, emotions). For each, enabled reports whether the enrichment is active for the tenant (deployment-configured and switched on / with a resolvable target language), and eligible/done are directory-level counts of feedback records that qualify and that have been enriched — the UI derives "in progress" as eligible - done, of which failed is retryable and failed_terminal never will be. When an enrichment is not enabled its counts are zero and disabled_reason names the gate that closed it, so the UI can explain why rather than silently hiding the enrichment. as_of is when the counts were computed, which lets a polling client derive throughput and an ETA without the Hub computing either. The response contains counts only (no record identifiers or content).
