Alerting: Error on alert state history load: ruleUID is required to query annotations

### What happened? As soon as I try to access the alert state history page, it stays empty even though alerts were active in the past, and outputs the following error message: ``` Something went wrong loading the alert state history ruleUID is required to query annotations ``` Screenshot:  Entering filters does not help and still produces the same error message. Grafana built-in alert manager is used, no other alert manager is and was ever configured. ### What did you expect to happen? The alert state history page loads without error and displays past alerts as shown the [documentation](https://grafana.com/docs/grafana/latest/alerting/monitor-status/view-alert-state-history/#view-from-the-history-page). ### Did this work before? The alert state history has not worked before on this installation, as it was just recently upgraded from a previous version which did not support the feature (11.1, if memory serves) to the most recent OOS version (12.0.2). The corresponding feature flag was enabled after the upgrade, using a Docker environment variable. ### How do we reproduce it? 1. Upgrade to current Docker container image 2. Enable ```alertingCentralAlertHistory``` feature flag, i.e. add ```GF_FEATURE_TOGGLES_ENABLE=alertingCentralAlertHistory``` to the Docker compose file in the environment variable section 3. Navigate to Alerting -> History Seams to be a problem specific to our installation, as I could not find any other reports of the error message appearing in the alert state history. Further troubleshooting is probably required, any help is appriciated 😃 ### Is the bug inside a dashboard panel? _No response_ ### Environment (with versions)? Grafana: Grafana OOS v12.0.2 (5bda17e7c1) OS: Docker image, Docker version: Community 28.1.1, Kernel version: 6.5.13-1-pve (Docker container running inside LXC container running on [Proxmox](https://www.proxmox.com/en/)) Browser: Firefox …
