feat: add support for env name from auth (#410)

* add support for env name from auth
* use only env name in auth call and cache

closes [Support non-slugified environment names](#407) #407
* Environment name will be returned in auth call in addition to slug.
* Environment slug is no longer supported in the rules file. If it becomes an issue and there is high demand for it, we can consider adding it as an option later.
* Using the environment name instead of the slug is more intuitive for end users, as they set the environment name intentionally, not the slug. This can now be used in the rules config instead of worrying about the structure of the slugified version of the environment.
