* fix: stop underestimating is_empty / not-null cardinality by 1/3

Re-introduce #10128 after its revert so CI can exercise
payload_index_test::test_read_operations / test_is_empty_conditions.

* test: stop requiring is_empty struct exp to beat plain

NullIndex complement estimates use an indexed upper bound (may include
soft-deletes); that is not guaranteed to be closer to truth than plain's
available/2 guess. Assert upper-bound semantics instead.

* test: drop is_empty exp==max assertion

That locked in NullIndex implementation detail. Keep result parity and
min/max bounds only; document why exp-vs-plain is not checked.
