Acquisition Funnel

Windowed acquisition-funnel rollup. Each stage counts rows whose OWN lifecycle timestamp falls inside the last days days — stages are therefore independent tallies, not a strict subset chain (a creator discovered 40 days ago who claimed yesterday counts in claimed but not discovered for days=30).

funnel.repair_sent is windowed on the ledger's sent_at stamps like every other stage (2026-07-16 revenue-accuracy fix — it previously rendered the ALL-TIME ledger size beside windowed stages). The all-time ledger size now lives at all_time.repair_sent (additive to the frozen shape).
