fix: widget sensitivity not changing on subcategory change

[weibullguy]

Does this PR introduce a breaking change?

• Yes
• No

Describe the purpose of this pull request.

To fix the problem with the widget sensitivity not changing when the subcategory was changed without running a calculation or deselecting and reselecting the changed component.

Describe how this was implemented.

Removed the _do_set_sensitive() listener method in the Panel metaclass. Removed the lines that loaded the widgets in the _do_set_sensitive() methods; the widgets should be blank anyway after selecting a new subcategory. Set each component type's _do_set_sensitive() method to be called whenever the subcategory is changed.

Describe any particular area(s) reviewers should focus on.

None

Provide any other pertinent information.

Closes #978
