The newly added test code fully covers the changes made in this update.

behavioral regression in filters/utils.go: the original loop sets match := len(sub) == 0 -- an empty sub-slice is a wildcard (matches any topic at that position). slices.Contains(sub, ...) on an empty slice returns false, so a filter like [][]common.Hash{{}} now rejects all logs at position 0 instead of accepting all. this breaks the ethereum filter spec.

test gap: the test case named "empty topic sub-array (wildcard)" uses topics: [][]common.Hash{} (empty outer array), which skips the loop entirely and doesn't exercise the broken path. add a case with [][]common.Hash{{}} (one empty inner slice = position-0 wildcard) and verify it still returns all logs.

the authz.go change is correct and clean.
