Editing on sybtype group layer is failing in Manager

[azizaparveen]

Describe the bug

Reference issue : https://github.com/Esri/solutions-components/issues/846#issuecomment-2339696034 This fails in the edit-card code when the code tries to add an event on layer edit, and the on is not available on the layer instance. This seems to be a specific issue to this web map only and could be due to the subtype group layers

Expected Behavior

Editing should not fail

Test app: https://solutions.mapsdevext.arcgis.com/apps/instant/manager/index.html?appid=6c07ac143e0741908d988bc9aa00f451 1) launch the app 2) Select a record from water Device layer 3) Click Edit button and update a value and click Update 4) Notice that Editing panel goes blank and console error shows up/
