Re-enable state root computation in blockchain node

- Fix chain_id mismatch (ait-devnet -> ait-mainnet)
- Add logger definition to poa.py for state root computation
- Recompute state_root after genesis account initialization
- Create genesis.json with account allocations for ait-mainnet
- Update config.py supported_chains to ait-mainnet
