Background / details

Service settings:

• Port
• Service log level
• Token expiry time (show if the data is there but read only, hide otherwise)

In https://github.com/vegaprotocol/vegawallet-desktop/pull/505 we introduced two new handlers to retrieve / update service specific settings. We need to figure out a place where we can display them on the UI, and allow the user to update the parts which make sense updating.
