Add plot_surface to display a triangular mesh (vertices, faces) as a napari Surface layer, with an optional per-vertex values array for colormapped shading. Pairs with Atlas.get_mesh to overlay BrainGlobe atlas region surfaces on the reference template or a registered fUSI volume; because both live in the same physical space, the surface aligns without extra scaling. Closes #262

napari opens in 2D, where a Surface layer is drawn only as its cross-section with the current slice plane, so a 3D mesh is all but invisible. plot_surface now switches the viewer to 3D rendering and resets the view to frame the mesh.
