AP-5273: SCA level of service fix

Link to story

Update the SubstantiveDefaultsForm handling of the default level of service

On a non-sca proceeding the view stores default values and passes them as controller params to the form.

The SCA skip removed the submission of these and meant that the default LOS was not set

This updates the test to ensure the proceeding is instantiated in the same way that it occurs in the controller, i.e. no default values populated for the three substantive default level of service fields. It then updates the form to set the value using the values called from LFA and stored as form values

Checklist

Before you ask people to review this PR:

• Tests and rubocop should be passing: bundle exec rake
• Github should not be reporting conflicts; you should have recently run git rebase main.
• The standards in the Git Workflow document on Confluence should be followed
• There should be no unnecessary whitespace changes. These make diffs harder to read and conflicts more likely.
• The PR description should say what you changed and why, with a link to the JIRA story.
• You should have looked at the diff against main and ensured that nothing unexpected is included in your changes.
• You should have checked that the commit messages say why the change was made.
