refactor(ui): Isolate world coordinate space

This change updates the topology view in the OpenDC frontend to isolate
the world coordinate space. This means that zooming and panning should
not affect the coordinates in world space (but only in camera space). In
turn, this allows us to remove the dependency on Redux for the camera
controls.
