Currently released bundle deploys identity-platform-login-ui-operator v0.24 which breaks the platform

### Bug Description

Hey team,
Last week we noticed our integration tests started to fail with the iam bundle (see [here](https://github.com/canonical/opensearch-dashboards-operator/actions/runs/19925910399/job/57126607869)). After investigations we pinpointed the issue to be that the released bundle does not have a default value for identity-platform-login-ui-operator's OCI image so it takes the default one from the charm itself. 3 weeks ago that value was changed to 0.24 which broke the platform.

Specifying the image fixes the problem see our temporary fix [here](https://github.com/canonical/opensearch-dashboards-operator/pull/224/files#diff-59e5998ea4461b9314ec56c5b2ea69696d7ce678a32d17570891642fa2f6615a)

### To Reproduce

- Deploy the currently released bundle
- Integrate a product with it

### Environment

Bundle deployed was `latest/edge`

### Relevant log output

```shell
https://github.com/canonical/opensearch-dashboards-operator/actions/runs/19925910399/job/57126607869
```

### Additional context

_No response_

Start with the iam bundle configuration and the temporary fix linked in PR #224. Reproduce with the latest/edge bundle and verify how the identity-platform-login-ui-operator image is sourced. Done means the released bundle explicitly pins the compatible image instead of inheriting the charm default, and the integration deployment no longer fails.
