[IMP] survey: rename and improve statistics fields

Purpose is to clean a bit those fields. A field holding the number of send
invitations is added as well as a button. It allows to directly jump on
answer linked to an invite which helps dealing with private surveys.

This commit is linked to task ID 1935176 and PR #30689 .
