Add Duplicate Button and Functionality to home_view.dart

[mahendra-918]

Description

This PR adds a "Duplicate Alarm" button to the home_view.dart file alongside the existing "Preview Alarm" and "Delete Alarm" buttons. The duplicate button allows users to create a new alarm with the same settings as the selected alarm. The necessary functionality is implemented in the HomeController.

Proposed Changes

AlarmModel (alarm_model.dart):

Added the clone method. HomeController (home_controller.dart):

Added the duplicateAlarm method. HomeView (home_view.dart):

Updated the PopupMenuButton to include the "Duplicate Alarm" option and linked it to the duplicateAlarm method in the HomeController.

Fixes #650

Replace '650' with the issue number which is fixed in this PR

This should ideally only work for non-shared alarms within a single profile only. We can later look into making this possible for shared alarms too.
