v3.0.3

Fixed

• The GridImagePicker image-action dialog now closes only itself. It used to close whatever route was on top of the grid's navigator: dismissing the dialog while a delete or set-main request was running closed the grid's page once the request finished, and a route pushed over the dialog was closed in its place. Inside a nested navigator, such as a go_router ShellRoute, Back and finished requests closed the page under the dialog and left the dialog open.
