fix(fiat): Set @EnableFiatAutoConfig to avoid unnecessary auth requ…

…irements (#286)

Original intention was to not require full blown `fiat` to use
`FiatStatus` but unfortunately spring security is brought in as a
transitive dependency.

This PR is a simpler alternative to moving `FiatStatus` and the
related configuration properties classes to a new artifact that
would not bring in any unnecessary dependencies.
