Remove Postiz authentication variables and related configurations

- Deleted POSTIZ_USERNAME, POSTIZ_PASSWORD, and POSTIZ_PASSWORD_HASH from .env.example and docker-compose.yml to streamline configuration.
- Removed basic authentication setup from Caddyfile for the Postiz service.
- Updated scripts to eliminate generation of Postiz-related secrets, enhancing security and simplifying setup.
