fix(render): highlight untinted analytical curves and guard uniform bind group

- Fall back to WireModel::SELECTED when selected_tint is None (classic mode) so selected circles, arcs, and ellipses are not omitted from the highlight pass.

- Explicitly rebind uniform_bind_group before drawing analytical curves in selection_xray pass.

- Skip invisible wires (display_visible == false) during selection and hover wire extraction.
