Added layer of security, we encrypt the API key and related secret.
It requires setting up some encryption keys that can be generated wiht
`bin/rails db:encryption:init`
The VINE Api require a secret and an API key to be used. The secret is
used to sign the request. The secret is linked to the API key so we need
to store it along side the key.
Most production servers don't use the source locale `en`. Even if the
default language is English, they use a local variant like `en_AU` or
`en_GB` to customise some of the translations.
However the environment is configured, the app should always fallback to
`en` if no other translation is available.
