Show trade volume for pair under pro orderbook

[smk762]

Closes https://github.com/KomodoPlatform/komodo-wallet-desktop/issues/2382 and https://github.com/KomodoPlatform/komodo-wallet-desktop/issues/2384

To test:

• Confirm pairs match values at https://defi-stats.komodo.earth/api/v3/gecko/tickers
• Confirm reverse pair shows same values
• Confirm segwit / non-segwit pairs show same values
• If pair not in list on API, or zero volume traded, volume text should not display
• Confirm values update on fiat settings change as expected.
• Confirm pro view combo box text changes as expected when changing currency via menubar

@smk762 trade volume works only for USD currency. If I use any other currency volume is zero e.g. GBP
