Bug description

Can't login because of error related with currency

Steps to reproduce

1. Open https://app.monicahq.com
2. Login with my username and password
3. Error "Cannot find ISO currency HRK" is displayed. I can't proceed...
   

For some contacts I have some debts written. The currency for the amount was set to Croatian Kuna (HRK). Since 2023. HRK is no longer active currency (Croatia switched to Euro) so this is why the HRK is missing in some ISO currency list.

Expected behavior

Application should login successfully even if some debts are written in older, no longer active currencies.
Alternatively, amounts in HRK should be converted to Euro, the official exchange rate for HRK to Euro was. 1 Euro = 7,53450 HRK.
