Fixes #2166

[7h3kk1d]

• Exp.cls_of_term shows cls of underlying expression if projector
• Cursor inspector still shows projector info on left side

[7h3kk1d]

@disconcision I did the most tactical thing here. I'm not sure what we want cls on info/expression to be. This still uses the override in the cursor inspector to show the projector info but now error messages have the underlying expressions cls.

Sidenote, this just reaffirms my belief that building all this stuff in statics makes more sense than a set of attributes that are universally applicable.

building all this stuff in statics

like building the CI in statics? yeah probably reasonable at this point
