Fix subplot_of_mapper crash on interferometer data_subtracted

Panel 0 of `subplot_of_mapper` and `subplot_mappings` passed
`inversion.data_subtracted_dict[mapper]` directly to `plot_array`, which
expects a 2D array. For interferometer fits the entry is `Visibilities`
(1D), so `plot_array`'s `array.shape[:2]` unpack failed.

Mirror the existing `Visibilities` check in panels 1-3: when the dict
entry is `Visibilities`, transform to a 2D dirty image via
`inversion.transformer.image_from(...)` (same mechanism as
`FitInterferometer.dirty_residual_map`). Imaging path unchanged.
