Add support for connecting a lateral to a parent well from Python (#12613)

* Updates well path connection logic.

Refactors well path connection to ensure tie-in location is updated correctly after connecting to a parent well. This ensures the visualization and data consistency are maintained.

* Updates connected editors after target manipulation

Ensures that connected editors are updated whenever the target is manipulated through the 3D manipulator.

* #12613 Adds functionality to append lateral well paths
