Revenue report always returns zero (filters non-existent fields)

Severity: High · Where: misc.ts:384 (live) Filter checks e.revenue/e.eventName; stored fields are e.value/e.name. The event.value fallback at :393 is dead code. Routes /api/sites/{id}/revenue and /api/p/{id}/income are live. Impact: Headline e-commerce metric broken end-to-end. Fix: Filter/sum on value/name.
