New Case Contacts Table: new case contact button (#6859)

feat: add New Case Contact button to new design case contacts page

Adds a primary-styled button to the header of the new design case
contacts table that links to the existing new case contact flow.
Accessible (aria-hidden on decorative icon) and responsive (flex-wrap
on narrow viewports). Covers admin and volunteer roles in system specs.
Spec structure aligned with shared_context pattern from b4758d1 to
minimize future merge conflicts.
