Subject: Fixed #13883 -- Rendered named choice groups with <optgroup> in
 FilteredSelectMultiple.

This patch adds support for <optgroup>s in FilteredSelectMultiple widgets.
When a popup returns a new object, if the source field contains optgroup
choices, the optgroup is now also included in the response data.

Additionally, this adds error handling for invalid source_model parameters
to prevent crashes and display user-friendly error messages instead.
