fix: update default values for WA_BUSINESS configuration

Updated the default values for TOKEN_WEBHOOK, URL, and VERSION in the WA_BUSINESS configuration. This change ensures that the application has more meaningful default settings, improving the initial setup experience. The impact is limited to default behavior when environment variables are not set.
