When running `helm upgrade --install` on a non-existent release, the
--server-side flag was not being passed to the install action. This
caused the install to always use server-side apply (the default),
ignoring --server-side=false.
Copy ServerSideApply and ForceConflicts from the upgrade client to the
install client when falling back to install.
Fixes#31627
