[DDW-427] Handle new transaction fee calculation error messages

[nikolaglumac]

This PR introduces more granular error messages for transaction-fee-calculation Api endpoint:

Amount + fees exceeds walletBalance:
- error.diagnostic.details.msg === 'Not enough coins to cover fee.'
= show "Not enough Ada for fees. Try sending a smaller amount."
-----
Amount exceeds availableBalance due to pending transactions:
- error.diagnostic.details.msg === 'Not enough available coins to proceed.'
- total walletBalance > error.diagnostic.details.availableBalance
= show "Can not calculate fees while there are pending transactions."
-----
Amount exceeds walletBalance:
- error.diagnostic.details.msg === 'Not enough available coins to proceed.'
- total walletBalance === error.diagnostic.details.availableBalance
= show "Not enough Ada. Try sending a smaller amount."

Todo:

• Bump Cardano version in cardano-sl-src.json to the commit which contains the fixed Api error response ([CBR-464] Raise Correct CoinSelHardErr during coin selection cardano-sl#3710)
• Inject missing Japanese translations:

"api.errors.CanNotCalculateTransactionFeesError": "Can not calculate fees while there are pending transactions.",
"api.errors.NotEnoughFundsForTransactionError": "Not enough Ada. Try sending a smaller amount.",
