What this PR does:

This PR enhances the wallet's transaction processing capabilities by implementing support for proper storage deposit event parsing and handling.

Key Changes:

1. Updated Storage Deposit Event Types:

   • Changed event type identifiers from legacy format (StorageDeposit, UnlockDeposit) to proper protobuf type URLs (/tm.StorageDepositEvent, /tm.StorageUnlockEvent)

2. Improved Event Parsing Logic:

   • Replaced manual attribute parsing with proper protobuf decoding using StorageDepositEvent and StorageUnlockEvent
   • Simplified parsing by directly accessing bytes_delta and fee_delta/fee_refund fields from decoded events
   • Removed complex string parsing logic for storage usage calculation

3. Streamlined Data Processing:

   • Storage deposits now use absolute values of fee_delta and bytes_delta directly
   • Eliminated the need for custom parseStorageUsage function
   • Improved accuracy in storage cost calculations
