Reverse-resolve a batch of Ethereum addresses to ENS primary names + avatar URLs (up to 50 per call). Returns one row per address with name (or null), displayName (with checksum if no name), and avatar URI. Use to label transaction lists, wallet leaderboards, or NFT holder snapshots with human-readable names instead of 0xabc… stubs.
