[TASK] Avoid implicitly nullable class method parameter in `EXT:adminpanel`

With PHP 8.4 marking method parameter implicitly nullable
is deprecated and will emit a `E_DEPRECATED` warning. One
recommended way to resolve this, is making it explicitly
nullable using the `?` nullable operator or adding a null
type to an union type definition. [1]

This prepares the way towards PHP 8.4 compatibility.
