refactor: Improve filter case sensitivity in query handlers

Updated the filtering logic in AlarmHistoryQueryHandler, AlarmRuleQueryHandler, and WebHookQueryHandler to perform case-insensitive searches by converting both the filter and the target display names to lowercase. This enhancement ensures more accurate search results regardless of the case used in the input.
