[KYUUBI #6314][SPARK] Preserve lineage for JDBC temporary view inserts

[wayne-x-wang]

Why are the changes needed?

Inserts into JDBC temporary views resolve to InsertIntoDataSourceCommand with no target catalogTable. The guarded map throws a MatchError, so lineage extraction fails even though the write succeeds.

Preserve query column names and source lineage when target catalog metadata is absent, matching the existing SaveIntoDataSourceCommand behavior. outputTables remains empty; this change does not infer a JDBC destination identity. Catalog-backed inserts keep their existing behavior.

Fixes #6314.

How was this patch tested?

Added an embedded Derby regression that creates a JDBC temporary view through SQL, executes an insert, reads the stored row through JDBC, and checks the command type, absent catalogTable, source tables, column mappings, and empty output tables. It checks both parse and transformToLineage. Without the fix, two separate JVM runs failed with the same MatchError. Existing tests cover inserts with target catalog metadata.

Spark 3.5.8 / Scala 2.12: all 77 lineage tests passed.

Spark 4.2.0 / Scala 2.13: the JDBC temporary-view regression passed.

dev/reformat, Spotless, Scalastyle, and git diff --check passed. The historical Kyuubi 1.8.0 / Spark 3.2.3 combination and MySQL were not tested.

Could a maintainer please re-run the failed jobs? All 77 lineage tests passed. The two failures are in EngineRefWithZookeeperSuite and the ZooKeeper 3.7 integration test, outside this patch’s changes.
