  Interactive OK/BYE block for a @mailman invite Line — Phase A of the my-sea
  invite flow ([[my-sea-invite-voice-blueprint]]). Renders entirely from
  `line.sea_invite.status`; the {% if line.sea_invite %} guard lives in
  post.html so this partial is only reached for invite Lines.

  PENDING (not expired) → OK / BYE form buttons (POST accept / decline).
  ACCEPTED → "Accepted {date}" badge. (VISIT link to the owner's table is
             added in Phase B once `my_sea_visit` exists.)
  DECLINED → "Declined" · LEFT → "Left {date}" · else → "Expired".
