fix(journey-client): extend JourneyClientConfig from AsyncLegacyConfigOptions

Allow the same config object to be shared across journey-client,
davinci-client, and oidc-client. Properties like clientId, scope,
and redirectUri are accepted but not used — a warning is logged
when they are provided.

+Extend `JourneyClientConfig` from `AsyncLegacyConfigOptions` so the same config object can be shared across journey-client, davinci-client, and oidc-client
+
+- `clientId`, `scope`, `redirectUri`, and other inherited properties are now accepted but ignored — a warning is logged when they are provided
+- `serverConfig.wellknown` remains required
