3157: Fix v6.0.0 plot scaling issues

[krzywon]

Description

This is a lesser implementation of the work already in #3148. This fixes the plot scaling issues introduced in v6.0.0, but doesn't make as clean a separation of the data and plots as I originally hoped to make for the release.

Refs #3021 (A start for this, but doesn't fully remove the x/y transforms from PlotterData classes and still uses them in a couple of places)
Fixes #3157

How Has This Been Tested?

Tested from source on Win11. Verified the following:

• SAS data and fits are plotted together on log/log scale
• SAS residuals are on log/lin scale
• SESANS data and fits are plotted together on lin/lin scale
• SESANS residuals are on lin/lin scale
• All residual plots (SAS and SESANS) have the +/- 3 lines
• Polydispersity plots are on lin/in scale
• No change to 2D plot scaling
