✨(frontend) Teacher dashboard: Page course signatures

[rlecellier]

Feature Request

This issus is similar to the "Page organization signatures" issus

• Add "signatures" entry on TeacherCourseDashboardSidebar
  ⚠️ This entry is visible for users with at least one organization with the abilitiy "can_sign_contract"

• Create MSW endpoint to list contract (see backend issus)

• Create page "signatures" based on this sketch preview
  This page use a cunningham DataList to display all contract that an need to be sign for this course and all user's organization with "can_sign_contract" ability.
  Do not display contract that are already signed by the organization.

  • The DataList must have a global action Sign all.
  • Each row must display:
    • Selection checkbox
    • Learner name
    • Product title
    • Button sign

Do not implement sign process here, it will be done in a dedicated issus
