Show Confirmation and Information Panel for Deleting a Person

[Japoivvb]

Describe the solution you'd like
Currently, when a person is deleted using handleDeletePerson(), the action is performed without any confirmation prompt or success message. To improve user experience, we should:

1. Ask for confirmation before proceeding with the deletion.
2. Show an information pane once the deletion is completed.

Additional context

• Display a JOptionPane option dialog before deleting a person.
  Message: "Are you sure you want to delete this person?"
  Options: Yes / No
  Proceed only if the user confirms.

• If confirmed, execute deletion and then show an information pane confirming the deletion.
  Message: "Person deleted successfully!"
