What changed (plus any additional context for devs)

This PR migrates transaction-related API calls from the Addys service to the Platform service. The changes include:

• Updated consolidatedTransactions.ts to use the Platform API endpoint for listing transactions

• Updated transactions.ts to use the Platform API for transaction listing
• Added Platform transaction type definitions in src/core/types/gen/plattform/transaction/transaction.ts
• Added utility functions to convert Platform transaction responses to the existing API response format

What to test

• Verify that transaction history loads correctly in the UI
• Check that transaction details can be viewed for individual transactions
• Ensure pagination works when scrolling through transaction history
• Confirm that transactions appear with the correct status (pending, confirmed, failed)
• Test across different networks to ensure chain-specific transactions load properly
• Verify that transaction filtering works as expected
