Add WalletDb Initialization to StorageNode::new() in src/storage.rs

[Sophie-Ag00001]

PR Description: Enhance WalletDb Initialization in StorageNode

Summary of Changes

This pull request updates the StorageNode::new() function in src/storage.rs to include a new initialization for the WalletDb. The implementation mirrors the existing WalletDb initialization found in src/miner.rs, ensuring consistency across the codebase.

Motivation

The motivation for this change stems from a need for uniformity in how the WalletDb is initialized throughout the application. By adopting a similar initialization pattern in StorageNode, we aim to enhance code maintainability and clarity, aligning with best practices.

Relevant Context

The WalletDb is a critical component that handles wallet data management. Ensuring that it is initialized correctly in multiple locations within our codebase helps prevent potential runtime errors and streamlines future updates. The specific requirement to work solely within src/storage.rs was adhered to, maintaining the integrity of other components.

Testing Instructions

To test the changes made:

1. Review the StorageNode::new() function in src/storage.rs to ensure the WalletDb initialization has been properly integrated.
2. Compile the application to check for any errors post-update.
3. Run existing unit tests related to the storage node to confirm that no regressions have been introduced.
4. Manually verify the functionality of the storage node to ensure that it correctly interacts with the initialized WalletDb.

Known Issues or Limitations

• No known issues were identified during the implementation of this feature. As this change is isolated to src/storage.rs, it should not affect any other functionalities. However, additional testing in related areas is always recommended to ensure stability.
