fix: report Coolify deployments to GitHub with branch-aware refs

[joaomnuno]

Changes

• Adds GitHub Deployments API sync for GitHub App sources and stores the deployments: write permission.
• Creates deployment records when Coolify starts a deploy and updates them to in_progress, success, failure, or error.
• Uses the branch ref for normal deployments and refs/pull/{pr}/head for preview deployments so GitHub attaches preview deployments to the PR branch.
• Fixes automated GitHub App registration by using the live webhook endpoint and removing the invalid manifest callback URL.

Issues

• Fixes [Bug]: Preview GitHub deployments are not associated with the PR branch #9583
