+/**
+ * POST /api/admin/billing/backfill
+ *
+ * One-off bootstrap that reads every live PiecedTenant CR and
+ * mirrors it into the Phase 1 billing tables:
+ *   - tenant_billing_lifecycle.created_at ← CR's creationTimestamp
+ *   - tenant_skill_events: one 'enabled' event per package in
+ *     spec.packages, anchored at the CR's creationTimestamp
+ *   - tenant_suspension_events: one 'suspended' event if the CR is
+ *     currently suspended (anchored at status.suspendedAt)
+ *
+ * Idempotent — re-running is safe. The helper only inserts rows
+ * for tenants that have no lifecycle row / no events yet; running
+ * twice produces zero additional rows.
+ *
+ * Authorization: platform role only. The body of the request is
+ * ignored.
+ *
+ * Response: counts of rows inserted, mostly for sanity-checking
+ * (expect non-zero on first run, zero on subsequent runs).
+ *
+ * Phase 2 will surface this behind an admin UI button.
