Pipe: Avoid invalid leader cache hints for table-model batches

[Caideyipi]

Description

Pipe tablet batch responses carry per-row redirection statuses. Table-model InsertTabletStatement and InsertRowsStatement batches can contain multiple device IDs, so attaching a single statement path to those statuses can create invalid leader-cache entries and misroute later writes.

This change:

• keeps redirect device-path metadata for tree-model row and tablet batches;
• omits per-row leader-cache hints for every table-model batch statement;
• ignores redirect statuses without a non-empty device path and tolerates malformed nested statuses;
• adds regression coverage for table-model tablets, table-model rows, tree-model batches, and malformed cache responses.

Validation

• Manual compilation of both changed production classes and both changed test classes against the existing DataNode artifacts.
• JUnitCore: 23 tests passed for IoTDBDataNodeReceiverTest and LeaderCacheUtilsTest.
• mvn -pl iotdb-core/datanode spotless:check '-DskipTests' '-Dcheckstyle.skip=true' passed.
• git diff --check passed.

The normal Maven test invocation is blocked by pre-existing stale cross-module generated artifacts/dependencies in the checkout (TypeServices, ANTLR, and Thrift symbols in unmodified files); the changed classes compile independently and the targeted tests pass.
