Implement nested Safe info in Result page

[ferrabled]

Description

The result page currently doesn't display information about nested safe transactions. When a transaction involves a nested safe, users need to see the nested safe's details (address, nonce, version) in the result page to properly verify the transaction.

Current Behavior

• Result page only shows the main transaction details
• No visibility into nested safe information when present
• Users cannot verify nested safe transaction parameters

Changes Needed

1. Add a new section in the result page for nested safe information:

   • Display nested safe address with avatar
   • Show nested safe nonce and version badges

2. Implement proper conditional rendering:

   • Only show nested safe section when result.nestedSafe exists
   • Maintain consistent styling with the main transaction section
   • Add appropriate separators between sections
