Alerting: Ensure case-sensitive ordering for alert rule group column

The query which fetches alert rules in a paginated manner ordered by `rule_group` can result in strange and inconsistent ordering when the database uses a case-insensitive collation for the `rule_group` column. This can lead to scenarios where rules from different groups are interleaved in the results, making pagination unreliable and the returned number of rule_groups incorrect. Related to #88990
