The {{port}} template variable was undocumented and caused a double port bug
when used in preview URL templates. Since ports are always appended to the final
URL anyway, we remove {{port}} substitution entirely and ensure consistent port
handling across ApplicationPreview, PreviewsCompose, and the applicationParser helper.
Also fix PreviewsCompose.php which wasn't preserving ports at all, and improve
the Blade template formatting in previews-compose.blade.php.

When a docker compose service has multiple comma-separated domains, the
generate() method was only processing the first domain and truncating the rest.
The issue was that Url::fromString() can't parse comma-separated URLs - it only
parses the first one.
Fixed by:
1. Splitting comma-separated domains with explode(',', $domain_string)
2. Processing each domain individually in a foreach loop
3. Generating preview URLs for each domain using the same template/random/pr_id
4. Joining the results back with implode(',', $preview_fqdns)
This ensures all domains get properly transformed for preview deployments.
Example:
- Original: http://domain1.com,http://domain2.com
- Preview: http://57.domain1.com,http://57.domain2.com
- Before fix: http://57.domain1.com,http (truncated)
