Deuro Savings Error Handling (#2340)

Browse Source 
* feat(deuro): Enhance gas fee handling and error management for Deuro Savings Transactions.

This change:
- Introduces DeuroGasFeeException to handle insufficient ETH for gas fees.
- Adds check for ETH balance before savings transactions to prevent failures due to insufficient funds.
- Updates savings transaction methods to include error handling.
- Adds UI feedback for transaction failures in DEuroSavingsPage.

* Fix conflicts

* Update cw_ethereum/lib/deuro/deuro_savings.dart
