fix(tests): CI green-up after union-bounds root fix

- filter_pushdown.rs: enable enable_hash_join_dynamic_membership_filter in
  test_hashjoin_hash_table_pushdown_{collect_left,partitioned} (they
  specifically exercise HashTableLookupExpr; membership default is now false).
- filter_pushdown.rs: refresh test_hashjoin_dynamic_filter_pushdown_collect_left
  and the force_hash_collisions branch snapshots (bounds only, no IN (SET)
  since membership is off by default).
- clickbench.slt, preserve_file_partitioning.slt, projection_pushdown.slt,
  repartition_subset_satisfaction.slt: regenerated for post-#22384 plan
  display + membership-off default.
- configs.md: prettier reformat (trailing whitespace).
