Allow plot of a DataFrame on a deformed mesh

### Description of the feature

The option to plot the mesh deformed exists for `DataFrame.animate` but not for `DataFrame.plot`.

### Steps for implementing the feature

Similar to `DataFrame.animate`, possibly using the `DataFrame._disp_wf` and the labels used to select the field to plot in the `DataFrame`.

### Useful links and references

_No response_

Compare DataFrame.plot with the existing deformed-mesh option in DataFrame.animate, focusing on DataFrame._disp_wf and the labels used to select the field. Trace how plot receives the DataFrame and mesh parameters, then verify that plotting supports deformation and the same field-selection behavior without changing existing plot behavior.
