Go-live checklist: the invite item lists who was invited

PR #19457. Captured from the branch's own dev server (stage data, Stripe key empty), signed in as the admin of a TEST company.

The item, ticked, with its invitee

• The checkbox is ticked (an invite went out) and the invitee is still listed: name, then whether they signed in.
• The Team link stays after the item is ticked.
• More than 12 invitees show a "+N more" chip. That case is covered by the DOM and unit tests, not this capture (the TEST company has one invited teammate).
