BLOG-65 Establish beta environment (#66)

### Description

- Change some environment variables implementation
- Nginx configuration:

  ```nginx
  server {
      server_name beta.squidspirit.com;

      proxy_pass_request_headers on;
      proxy_set_header Host $http_host;
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Forwarded-Proto $scheme;

      location / {
          proxy_pass http://127.0.0.1:10013/;
      }

      location /api/ {
          proxy_pass http://127.0.0.1:10014/;
      }

      listen 443 ssl; # managed by Certbot
      ssl_certificate /etc/letsencrypt/live/beta.squidspirit.com/fullchain.pem; # managed by Certbot
      ssl_certificate_key /etc/letsencrypt/live/beta.squidspirit.com/privkey.pem; # managed by Certbot
      include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
      ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
  }

  server {
      if ($host = beta.squidspirit.com) {
          return 301 https://$host$request_uri;
      } # managed by Certbot

      server_name beta.squidspirit.com;
      listen 80;
      return 404; # managed by Certbot
  }
  ```

- Podman kube configuration:

  ```yaml
    apiVersion: v1
  kind: Secret
  metadata:
    name: beta-blog-secret
  data:
    DATABASE_PASSWORD: {{BASE64_PASSWORD}}
