feat: add clear icon on defined name comment; fix: overlaying a value on clear icon

[kenny-not-dead]

close #xxx

I noticed that the values ​​in the input that have an icon for clearing the value overlap the icon itself. It's clickable, but I don't think that's supposed to happen. I noticed that there's already logic regarding the right margin for slots, so I decided to use a separate useEffect and add a check that would not conflict with slots, also in [] I deliberately did not add allowClear, since this caused an extra trigger, since the first time the value was entered, an indent would still be needed.

I also found it strange that the name itself had this icon in defined names, but the comment didn't have it.
