Extend open paths from endpoints with the Freehand tool and skip hidden layers in path edits (#4508)

Browse Source 
* Let the Freehand tool continue a selected open path from its endpoint and show endpoint overlays in the Freehand and Spline tools

* Share the closest-point search with the open path endpoint lookup, tally endpoint connections in a single pass, and rename the endpoint overlay function

* Skip hidden layers and use the feeds-aware transform in path point searches, path overlays, and Freehand point placement

* Map the Spline tool's merge goal with the feeds-aware transform so it matches the endpoint candidates

* Highlight the hovered open path endpoint in the Freehand and Spline tools
