fix(modal): remove non existant cls-panel option

[derrabauke]

The clsPanel option got renamed to selPanel which indicates the real usage of it. It's not a css class which will be added for user specifics, but it is a selector for the modal internally. It won't set any classes on the modal element and should be removed from the ember component arguments as well.

Further information:

• clsPanel -> selPanel
• it's only a selector, not a custom class definition

Looks good but this is a breaking change Misread it never worked, right?

Since it could not work since ~2019 I guess it's not. :shrug:
