Add event processor that filters verified Stripe webhooks to only process crypto payment_intent events (succeeded, processing, failed). Extracts amount (converted to microUSDC), currency, chain hint, and token hint from metadata. Duplicate event IDs are silently dropped for idempotency. Closes geminimir#7 Made-with: Cursor
