Integration and review fixes for #2367, #2369 and #2387

- #2369: its test joins the single ui-egui integration-test binary (tests/it), as main now builds them.
- #2367: a cell set to empty text is a blank entry and doesn't grow the AutoFilter (CodeRabbit).
- #2387: MOD's range check also covers the sign-corrected remainder (CodeRabbit).
