Live Network Statistics (/v3/statistics)

Orion continuously reduces every closed Stellar ledger into 12 Parquet statistics families (core, account-windows, account-activity, failure-codes, contract-functions, asset-transfers, payment-corridors, payment-participants, stablecoin-transfers, market-daily, market-liquidity, storage-mutations) plus native_ledger_summary.parquet and publishes them to Cloudflare R2 (history/v5/_derived/statistics/).
