GitHub auto-deploy does not trigger when webhook owner name is missing

[agentHits]

To Reproduce

1. Configure an application or Docker Compose project with the GitHub provider.
2. Enable auto-deploy for GitHub push or tag events.
3. Select a repository through the GitHub provider UI. Dokploy stores the
   repository owner from repo.owner.login.
4. Push a commit to the configured branch, or push a configured tag, with a
   GitHub webhook payload where repository.owner.login is present but
   repository.owner.name is missing or null.
5. Observe the GitHub webhook handler processing the event without finding the
   configured application or compose project.

Current vs. Expected behavior

Current behavior:

• GitHub push/tag webhooks can be received and verified, but auto-deploy does
  not start.
• The webhook handler matches configured applications and compose projects
  using repository.owner.name.
• The GitHub provider UI stores the owner using repo.owner.login.
• When the webhook payload does not include owner.name, the query uses the
  wrong owner value and returns no deployable resources.

Expected behavior:

• Dokploy should match GitHub webhook repositories using the same owner value
  saved by the GitHub provider UI.
• Push/tag webhooks with repository.owner.login should find the configured
  application or compose project and enqueue the deployment.

Provide environment information

Dokploy version: current canary before PR #4674
Affected source: GitHub App provider webhook
Affected trigger types: push, tag
Affected deployment types: application, Docker Compose
Environment-specific: no; this depends on GitHub webhook payload shape and stored provider metadata

Which area(s) are affected? (Select all that apply)

• Application
• Docker Compose

Are you deploying the applications where Dokploy is installed or on a remote server?

Both. The bug happens before the deployment target is selected because no
matching deployable resource is found.

Additional context

The proposed fix is already open in PR #4674:

• fix: use github owner login for webhook deploy matching #4674

The PR changes the GitHub webhook handler to resolve the repository owner as
repository.owner.login ?? repository.owner.name and adds regression coverage
for push application, push compose, tag deploy, and branch mismatch behavior.

Will you send a PR to fix it?

Yes. Proposed fix: #4674.
