Case 5 (DUJ1 template) uses `sample rows 3` on a table with 5 rows, but
only 1 row had a long string exceeding statistics_max_string_column_length
(1024). With `sample rows 3` reading only 3 of 5 rows, there was a ~40%
chance that the long row was missed and the assert_true guard never fired.
When missed, big_str completed normally with an empty skip message,
causing the test assertion to fail:
expected skip reason visible for col big_str, got msg=
==> expected: <true> but was: <false>
The fix makes all 5 rows have repeat('z', 2048) for big_str, so the
long-string guard always triggers regardless of which rows are sampled.
No other cases are affected: Case 1/2/6 use full-table analyze, Case 3
uses sample percent 100, and Case 4 explicitly expects the guard NOT
to apply (partition path).
