Fiat conversion toggle for Token values in Wallet

[linear]

It has been suggested that a fiat conversion feature would be beneficial within the wallet. This would allow users to toggle between different fiat currencies and view the current value of their CCD tokens (and all other ones in the wallet in their preferred currency.

Proposed Solution:

• Implement a toggle or dropdown feature allowing users to switch between available fiat currency options.

• For reference, we can consider using an approach similar to Revolut’s currency conversion feature: when users click on the amount, a currency picker pops up from the bottom of the screen, enabling quick and intuitive currency switching.

• Display the CCD token (and all other ones in the wallet) value in the selected fiat currency based on real-time exchange rates.
