test(jobs): add job-queue lifecycle integration test

Adds integrationTests/server/job-queue.test.ts covering the async job queue
pattern observed in production CSV-import and prerender-queue clusters.
Six cases: status lifecycle (CREATED→COMPLETE), elapsed time from
start/end datetimes, skipped-items count in the result message,
delete_records_before as a TTL job, concurrent submissions with
unique job IDs, and hdb_job having no cluster-wide replication.

Closes #1193

+/**
+ * Job queue lifecycle integration tests.
+ *
+ * Tests the async job queue pattern observed in production clusters (e.g. CSV
+ * importers and prerender job queues). Exercises the hdb_job system table via
+ * the Operations API, covering:
+ *
+ *  1. Status lifecycle — a csv_data_load job transitions CREATED → IN_PROGRESS → COMPLETE.
+ *  2. Elapsed time — end_datetime - start_datetime is non-negative once a job finishes.
+ *  3. Skipped items — duplicate-key inserts are captured in the job result message.
+ *  4. Job TTL — a delete_records_before job runs to COMPLETE, exercising the cleanup-job path.
+ *  5. Concurrent claim — parallel job submissions yield distinct job IDs and all complete.
+ *  6. Non-replicated local DB — hdb_job has no cluster-wide replication, staying node-local.
+ *
+ * Related: https://github.com/HarperFast/harper/issues/1193
