chore: updates support for Solana devnet chains

[zone-live]

Explanation

1. Removes the Solana mainnet filtering
2. Reorganizes data structure to support an account[] -> chain[] -> transactions

  nonEvmTransactions: {
    [accountId: string]: {
      [chain: string]: TransactionStateEntry;
    };
  };

3. Updates logic to reflect these changes
