- Use non-paginated /sql endpoint for Spark < 3.2 apps where the paginated API returns 404
- Handle per-execution planGraph failures in DataflintSQLPlanPage instead of failing the entire batch (fixes NoSuchElementException for apps missing plan data in KVStore)
- Fix catch block return type from JObject to JArray in both Spark 3 and Spark 4 SQLPlanPage
- Guard against non-array sqlplan response in frontend
