[Table Stream] Recreating a base table with the same name can make planner locks and scan targets disagree #67095

Problem

[Table Stream] Recreating a base table with the same name can make planner locks and scan targets disagree

Minimal reproduction path

Create a base table and Table Stream, drop the base table, recreate a table with the same name but a different identity, and issue a stream query while metadata locks are active. Verify that the planner lock target and the scan target resolve to the same table identity and that the old stream cannot scan the replacement table.

Expected result

Planner locks and scans address the same table identity.
