[Table Stream] Stream locking still uses the old base-table name after RENAME #67102

Problem

[Table Stream] Stream locking still uses the old base-table name after RENAME

Minimal reproduction path

Create a base table and Table Stream, rename the base table, then query the stream and inspect its metadata lock target. Repeat after a frontend restart or journal replay. Verify that locking and scanning follow the table identity rather than a stale table name.

Expected result

Rename does not leave stream locking on the old name or scanning an unintended object.
