Improve configuration for braille-outputting scripts

[NPavie]

This pull request modify braille outputting scripts (ending in to-pef) to use the new stylesheet-parameters endpoint as to complete and/or simplify the scripts settings by relying on user stylesheets.

Closes #198 Closes #207

Ok i forgot to test some things at first before making the PR but it should now be fixed.

The new UX is as following

• On braille outputting script, the form is first limited to input, stylesheet, page width and height
• A next button performs a preliminary form validation, checking if input is set.
  • On success, the form request the stylesheet parameters with the new endpoint

The ui then expects a stylesheetParameters with additionnal or modified script options to switch to the second page of the form.

• If no stylesheet is provided, an empty array is returned in this field, and the remaining default script options are displayed
• If a stylesheet is provided, the new endpoint is used to retrieve the parameters value, stored the result in the job stylesheetParameters field, and
  • on parameters that are already defined in the script, the job request is updated with the new default value
  • on new parameters, those parameters are converted to new options added to the job request
  • The script options that are used to compute the Script form UI is updated by merging the script options with the stylesheetParameters content
• A new button "Back" let the user go back to first page of the form to change input or initial options

I'm not sure if I fully understand, but I will find out by testing it. Will do that as soon as possible.

The Windows build failed: https://github.com/daisy/pipeline-ui/actions/runs/8618713899/job/23621741796. I guess this is because of the bug you reported.

@NPavie Testing it now. It does not seem to work when an input XML is given (with a style element in its head), but no style sheets. Is that because of a bug in the engine, or is it because of the UI?

Other observations:

• When I set the style sheets option to "https://raw.githubusercontent.com/daisy/pipeline-modules/master/scripts/html-to-pef/src/main/resources/css/_definition-lists.scss", the next button does not do anything. When I set it to a local file that includes @import url(https://raw.githubusercontent.com/daisy/pipeline-modules/master/scripts/html-to-pef/src/main/resources/css/_definition-lists.scss);, it does work. Not sure whether this is an issue in the engine or UI.

• The "_definition-lists.scss" style sheet gives me 3 options:

  • Group dt dd
  • Dt suffix
  • Dt separator

  These are auto-generated nice-names. Obviously the descriptions would be better if the Sass variables would have Doxygen comments. What is surprising to me is that the expanded description of these options is "Definition lists" in the three cases. I've spotted a bug in the engine that explains this.
