QoL: diffrent cursor icons for dragging node vs dragging input/output

### What problem are you experiencing?

Hello,

Often I want to drag a noodle from node A --> node B, but then I missclick the node itself and drag that around instead >:( Its very annoying, happens to me many times a day, I get surprised and frustrated. The ambiguous UI made me do the wrong action.

It drives me insane.

As you see in the screen shot, the pointer icons are the same, but they do different functions.

Should be an easy one you all right? ty <3

No source file, test, or entry point is named in the issue. Start by reproducing the two drag actions shown in the screenshots and locate the frontend code handling node dragging versus input/output connection dragging. Done means the cursor icons clearly distinguish these actions without changing their behavior.
