+/**
+ * JobsTab — operational content for the backups service page.
+ *
+ * Lifted from the old top-level `components/BackupsPage.tsx`. The three
+ * sub-tables (Jobs / Runs / Alerts) and their hooks are preserved verbatim.
+ *
+ * NOTE: the backup hooks currently query globally (no service_id filter).
+ * The backend gained `service_id` attribution in Slice 3, but the hooks don't
+ * yet accept a serviceId param. This tab shows ALL backups data for now;
+ * per-instance scoping by `instance.id` is a follow-up once the hooks gain the
+ * parameter.
