[Bug]: `image push` can push a different image tag than `latest`.

### I have done the following

- [x] I have searched the existing issues
- [x] If possible, I've reproduced the issue using the 'main' branch of this project

### Steps to reproduce

```console
container build -t :latest .
container tag :latest :123456
container image rm :latest

container image push :latest
```

### Problem description

Last image push command should throw not found error, but it pushes :123456 instead.
The built image has an annotation of :latest, so it's filtered in localImageMatches there, and the guard branch returns localImageMatches.first.

However, :latest tag is already deleted, and it should actually return nil.

### Environment

```markdown
- OS: 26
- Xcode: 26
- Container: main
```
