Description

This PR adds a generic ActionButton to replace all the duplicate buttons with same logic throughout the application, along with this the PR also refactors the Save or Update button in AddOrUpdateAlarmView widget by creating a separate widget for the button in a different file, while also differentiating the business logic from UI to improve code readability, maintainability, and separation of concerns.

Proposed Changes

• Created a new folder utils/widgets which will contain all the universal UI components to be created as a part of refactoring the application
• Created a new ActionButton Widget
• Created a separate widget file for the SaveUpdateButton, moving it out of AddOrUpdateAlarmView to enhance modularity.
• Separated UI and business logic by keeping the button's responsibility limited to rendering, while delegating logic to controller functions.

Fixes #654
