add 'next assessment stage' buttons to red flags and principles

[dave-mills]

This PR addresses a request to include a link to continue the next stage of the assessment within the current assessment:

On the Red Flags page

• a new save option is added: "Save and start principle assessment"

This is done by overwriting the default save options within Backpack. Instead, the buttons are included directly in the redline.blade.php template.

• NOTE: the new button is not technically a submit button, but it is linked to some javascript that will update the _redirect input value before submitting the form.
• the _redirect value is used in the redirect after saving, with a default set in case something goes wrong.

Principle Assessment

Similar to the red flags, a new option is added to take the user directly to the additional criteria assessment page. This option only appears when the organisation has additional criteria active. It is enabled when the assessment is marked as finalised and disabled when not.

Pulled latest code and performed testing in local env.

Create a new initiative, "Save" button caption is not correct...

It does not divert to assess principles. It goes back to initiatives page...

Create a new initiative, "Save" button caption is not correct...

Fixed by reverting to the previous save button trait setup.

It does not divert to assess principles. It goes back to initiatives page...

Fixed by harmonising how both "save and..." buttons work. Now both use the same startAssessment() method.

Thanks :)

Thank you Dave. It works well now. Now we have a very smooth process from creating new initiative to finalise additional assessments in one go.

P.S. I have also disabled additional assessment criteria, then created a new initiative and assessed them smoothly.
