Auto-sync queue levels from on-chain upgrades

When a queue member's MemberUpgraded event lands, their Level in the
rotation queue updates automatically (same op as the admin dropdown),
with a Telegram note. Current queue trued up against the chain: four
entries corrected (30, 35, 46 up to Ascensus; 56 down to Scintilla —
it had been set optimistically).
