Remove roll call related code

[kevinlee-06]

Description

This PR addresses the removal of the unimplemented roll call button from the OtherPage UI. The roll call feature is currently not available, and this change helps to clean up the interface by removing references to it.

Implementation

• Removed the rollCallRemind enum value from OnListViewPress.
• Commented out the related UI elements and event logging code for the roll call feature in the _OtherPageState class.
• Ensured that no references to the roll call feature remain in the codebase.

Testing Instructions

Please provide details on the steps required to review and test this PR.

• Review the other_page.dart file to confirm that all references to the roll call feature have been removed or commented out.
• Run the application and navigate to the OtherPage to ensure that the roll call button is no longer displayed.
• Verify that the application functions correctly without any errors related to the removed feature.

Additional Notes

This change is part of a larger effort to streamline the user interface and remove features that are not yet implemented. Future updates will include the reintroduction of the roll call feature once it is fully developed.
