Function render_admin_session_detail_json 

pub fn render_admin_session_detail_json(
    session: &AdminSession,
    current_token_hash: &str,
) -> Value

A session listing plus one member no CLI rendering needed: whether this row is the caller’s own live session.

render_admin_user_detail_json’s arrangement – the listing shape, cloned and extended, never the reverse. current_token_hash is the caller’s own session (never a session being looked at, which never has this member’s answer be true of itself in a useful way), so the web panel’s own sessions card can badge or relabel the row that revoking would sign the viewer out of, without teaching AdminSession anything about who is asking.
