CW-674: Enhance Exchange Flow - Add estimated receive amount and amount currency to Confirm Sending Details Page (#1547)

* fix: Improve exchange flow by adding a timeout to the call to fetch rate from providers

* fix: Adjust time limit for fetching rate to 7 seconds and add timelimit to fetching limits

* fix: Make fetch limits a Future.wait

* feat: Add currency for amount and estimated receive amount to confirm sending page for exchange

* fix: Remove unneeded code

* fix: Modify receive amount to reflect value coming from the individual exchange providers if available and ensure receiveAmount is calculated based on selected exchange provider's rate
