[Bug]: COOLIFY_BRANCH inconsistent when building and within run container

[mlitwiniuk]

Error Message and Logs

$COOLIFY_BRANCH behaves inconsistently between setting dynamic env variables and what's actually passed to container.

In ApplicationDeploymentJob it's set to $this->application->git_branch while bootstrap/helps/parser.php set's it to "pull/{$pullRequestId}/head"

Steps to Reproduce

1. Create new app with preview deployment enabled
2. Edit environmental variables and set (for preview) TEST=${COOLIFY_BRANCH} - this will be set to actual git branch
3. Deploy preview instance from any branch
4. Open deployed container and echo $COOLIFY_BRANCH - this will be set to "pull/PULL_REQUEST_ID/head"

Additional Information
