Currency selector for contract management

The new currency selector feature is now available in the edit contract functionality settings of each application. Admins can now choose different currencies for each contract by clicking on the drop-down button on the 'value' field.

If the selected currency does not match the workspace currency, the value will automatically convert to the default workspace currency. This conversion is based on the exchange rate from openexchangerates.org.

This feature will improve data accuracy for contract values and streamline the contract management process.
