Fix undefined variable $site in Caddy vhost view (#967)

- Pass `$site` variable to `ssh.services.webserver.caddy.vhost` view in `PHPSite`, `NodeJS`, and `LoadBalancer` site types.
- Fix `LoadBalancer` Caddy vhost rendering to pass `main` blocks as an array instead of a string, matching the view's `@foreach` loop.
