/**
 * Pilot Invitation Manager (brief "Build the Pilot Invitation Manager Under
 * Moderator Tools", 2026-09-14). Internal operations tool for HeavyHaul
 * Agent staff (§8) — not a public page. Gated on the internal flag (answer
 * 8) like every admin tool; a customer is sent to their dashboard.
 *
 * Filters live in the URL (?q=&state=&cap=&status=&page=) so a view can be
 * shared. Tolerates migration 0018 not being applied: shows a banner.
