Expected behavior
The amount values in the list and detail pop up should be true and accurate, not zero, without the requirement to navigate away and back to the page.

Found in
0.9.3 RC eb2b0b8

Additional context
Replication was attempted on other protocols.

• DOGE/UTXO unaffected
• ARRR/ZHTLC unaffected
• AVAX/EVM history delayed, unable to confirm at this time.
• IRIS/ATOM consistently display the aberrant behavior

A summary of the changes CodeRabbit can apply:

• Add an amount getter returning balanceChanges.netChange in lib/shared/utils/extensions/transaction_extensions.dart, replace amount.toDouble() with balanceChanges.netChange.toDouble() in lib/bloc/cex_market_data/profit_loss/extensions/profit_loss_transaction_extension.dart, and add imports for the new extension in lib/shared/widgets/transactions/transaction_list_item.dart and lib/shared/pages/transaction_details.dart so the UI correctly shows (including unconfirmed) ATOM/IRIS transaction amounts.

• Update transaction balance handling by adding a Rational amount getter (balanceChanges.netChange) in lib/shared/utils/extensions/transaction_extensions.dart, switch profit/loss balanceChange to use balanceChanges.netChange in lib/bloc/cex_market_data/profit_loss/extensions/profit_loss_transaction_extension.dart, and import the new transaction_extensions.dart in transaction_details.dart and transaction_list_item.dart to reflect and use the unified net-change logic.
