Delete the rotation queue; sponsors.json stays as the member directory

Marty (2026-09-19): delete it if it no longer serves a purpose. The public link has run on the
chain walk since the mode flip and the queue's active head never received a join. Gone:
active/waiting/qualified statuses, normalizeStatuses, activeSponsor, publicSponsorPayload, the
increment/activate/qualify/reset actions, the click counter, the auto-count/auto-advance/
level-sync block, the legacy queue branches in current-sponsor and the submit-id classifier,
the chatbot's "placements waiting" facts, and the queue columns and buttons in admin. What stays
is a member directory (name, parent, level, notes, contact email) because the payout alerts and
the feed's name map read it. The chain walk is the only company rotation now.
