Ponder 0.16 Migration & Address Normalization

Summary

This PR upgrades Ponder from v0.11.40 to v0.16.2 and implements address normalization across the indexer to ensure consistent address formatting.

Changes

Ponder Upgrade

• Upgraded ponder package from ^0.11.40 to ^0.16.2

Address Normalization

• Added getAddress from viem to normalize all addresses to checksummed format
• Applied normalization in:
  • Event handlers (delegation, transfer, voting)
  • Metrics handlers (circulating, delegated, supply, total)
  • Shared utilities (account creation, transaction handling, daily buckets)
  • ERC20 indexer

Why

Address normalization ensures that:

• All stored addresses follow the same format (EIP-55 checksum)
• Comparisons between addresses work correctly regardless of input format
• Data consistency is maintained across the database

Files Changed

• apps/indexer/package.json - Version bump
• apps/indexer/src/eventHandlers/* - Address normalization
• apps/indexer/src/indexer/scr/erc20.ts - Address normalization
• apps/api-gateway/schema.graphql - Schema updates
