feat: make chain ID check optional in blockchain sync verification

- Add CHECK_CHAIN_ID_CONSISTENCY environment variable to sync-verification.sh
- When set to false, warns about chain ID mismatches but does not fail
- Allows nodes to be on different chains (mainnet vs devnet) while still verifying sync
- Updated workflow to use CHECK_CHAIN_ID_CONSISTENCY=false by default
- Fixes CI failure where aitbc2 uses ait-devnet while others use ait-mainnet
