KCL: Fix cryptic error when using duplicate edges in fillet call (#5755)

Fixes https://github.com/KittyCAD/modeling-app/issues/4307

Now if you try to fillet the same edge twice in a single fillet command,
the error message is clearer, and the source range will highlight
the specific edges in the array which are duplicated.

Same goes for chamfer.

Note: although the Rust KCL interpreter sends back an array of SourceRange
for each KCL error, the frontend only puts the first one into CodeMirror
diagnostics. We should fix that: https://github.com/KittyCAD/modeling-app/issues/5754
