585, 1878, 3188: Fitting report improvements

[krzywon]

Description

This overhauls the fit reports and includes a number of new features. All plots from the results panel (including DREAM plots), smearing information, and the fit Q range (in addition to the data Q range) are now shown in the report.

I've added a method to capture the batch fitting report, but too many other things need to change to make that happen here.

Tested CI build #5559 on W11/x64. Used the 2% SDS example data and fit to sphere + hayter_msa with radius polydispersity using DREAM.

Example of the new report:
report_pr3870.pdf
And then again after plotting the polydispersity, P(Q) & S(Q):
report_pr3870_2.pdf

This PR brings useful new information. Happy to approve.

Functionally, does what it says. Have not reviewed the code.

[gonzalezma]

Code looks fine to me (just need to correct a docstring), but the part concerning the smearing info does not seem to work at 100%. I did a test selecting Instrumental Smearing = Custom Pinhole Smear: dQ/Q 1% and this info does not appear in the report.

[gonzalezma]

Please correct the docstring and check why the information about Instrumental Smearing is not captured.

[krzywon]

@gonzalezma: I updated the smearing to include custom values and updated the incorrect docstring.

[krzywon]

The failing unit tests are documented in #3904 and are fixed in #3906.

All good now. Approving.
