Created a cancellation confirmation dialog with an optional feedback option.

[krritik]

Aim:
Enhance the cancellation experience by implementing a confirmation dialog when users click the Cancel button. This dialog prompts users to confirm their cancellation choice and optionally provide feedback. Integrated across relevant pages, it offers default cancellation reasons tailored to each context and allows users to input custom reasons.

Actions Completed:

1. Created a new confirmation dialog for cancelling actions.
2. Integrated a feedback option within the cancellation confirmation dialog, offering dynamic options.
3. Developed a custom cancel button for the wizard controller to trigger the cancellation confirmation dialog instead of immediate cancellation.
4. Implemented the cancellation confirmation dialog with distinct cancellation reasons for various wizard pages.
5. Extended the cancellation confirmation dialog to cover cancellation after migration initiation.
6. Incorporated the cancellation confirmation dialog into different login migration pages for consistency and improved user experience.

Implementation :

1. Utilized radio buttons and an input box for feedback options, catering to both predefined and custom reasons.
2. Incorporated callback functions to handle dialog confirmation, ensuring adaptability across different scenarios.
3. Implemented callback functions in the WizardController to track cancellation events, providing valuable insights for analysis.
4. Replaced default cancel buttons with custom ones, initiating the cancellation dialog for a consistent user experience.
