The first pass before zone filling marks vias/pads as ZLO_FORCE_FLASHED if they're within the zone outline. However, if the fill doesn't actually reach the via/pad due to obstacles (tracks blocking the fill), the annular ring should not appear. After zone filling is complete, this change adds a second pass that re-evaluates each via/pad marked as ZLO_FORCE_FLASHED. If no filled zone polygon actually reaches the via/pad, the override is changed to ZLO_FORCE_NO_ZONE_CONNECTION. Also adds a QA test to avoid regressions on issue #12964 which was the catalyst for the status quo Fixes https://gitlab.com/kicad/code/kicad/-/issues/22010
