Please address the comments from this code review:
## Overall Comments
- In FlipClock.razor, the month container is wrapped in an `@if (ShowDay)` check instead of `ShowMonth`, so update the condition to use the new `ShowMonth` parameter.
- The JS `getDate` function only calculates `months` in the non-countdown branch and still returns it for countdown, leading to an undefined value—compute and return `months` in both modes.
- Wrap your `listMonth` querying and `setTime` calls in a guard (e.g. check if `listMonth` exists) to prevent null reference errors when the month element isn’t present.

         const hours = Math.floor(totalMilliseconds / (1000 * 60 * 60)) % 24;
         const days = Math.floor(totalMilliseconds / (1000 * 60 * 60 * 24));
-        return { days, hours, minutes, seconds };

The countdown branch returns a 'months' property that is never computed

'months' is returned without being calculated, so it will always be undefined. Please compute its value or remove it from the return object.

             setTime(listDay, days, countDown);
         }

Wrong variable assignment in month update block

Assign `lastMonth = months` after updating the UI to ensure month changes are tracked correctly.

 @attribute [BootstrapModuleAutoLoader(JSObjectReference = true)]

 <div @attributes="@AdditionalAttributes" class="@ClassString" style="@StyleString" id="@Id">

<issue_to_address>
Month display block incorrectly gated by ShowDay

The month list should be rendered based on `ShowMonth`, not `ShowDay`. Update the condition to `@if (ShowMonth)` to fix this.
