fix: correct transaction field mapping and standardize genesis path resolution in PoA consensus

🔧 Transaction Field Mapping:
• Change sender field from "sender" to "from" in transaction parsing
• Change recipient field from nested "payload.to" to direct "to"
• Change value field from nested "payload.amount" to direct "amount"
• Align transaction structure with RPC endpoint format

📁 Genesis File Path Resolution:
• Use standardized /var/lib/aitbc/data/{chain_id}/genesis.json path
• Remove
