17. As a user, I want to be able to delete a selected list

[trushmi]

Summary:

To improve the user experience and allow users to keep their lists tidy, implement functionality that allows users to delete a selected list directly within the UI.

Acceptance criteria:

• On the home page, add a delete button to every list the user has on the home page.
• If the user clicks delete, the system should show a message asking if the user is sure they want to delete the list and inform them that all items in the selected list will also be deleted. If the user confirm their choice, delete the list along with all its items.
• Create a deleteList function in firebase.js to remove a list from the Firestore database.

Notes:

Activating the "Delete" button should prompt a confirmation dialog. We want to give users a chance to confirm "destructive" actions.
