[MishNajam]

This PR fixes VEGA-2862 #minor :

• adds the manage restrictions details form
• adds a link to the form in the restrictions sections of the lpa-details page
• moves the manage restrictions details into it's own template
• returns an error when submitting the form with no option selected
• returns a not implemented yet error when selecting severance is required when the restrictions task is open
• clears the restrictions task when severance is not required
• adds unit and cypress tests

Checklist

• I have checked that my UI changes meet accessibility standards
