Explorer GraphQL API

Hasura v2.29.0 GraphQL engine serving the Explorer v2 data layer. Tracks 51 PostgreSQL tables and 3 analytics functions (recent_gas_stats, gas_price_tiers, gas_price_by_day). Provides real-time queries for blocks, transactions, validators, staking data, EVM tokens, and address labels. Used by the Explorer v2 frontend via Apollo Client. Health depends on both PostgreSQL and the Callisto indexer keeping data fresh.
