fix: refactor chain selection logic in blueprint_batch_mint.ts

- Introduced separate arrays for testnet and production chains for better organization, and because .testnet property is not always defined in viem.
- Updated chain selection logic to determine if the selected chain is a testnet based on the new structure.
