Add confirmation modal to project deletion (superuser)

User story

As a superuser, I would like to be able to confirm the project name before I delete it, so that I don't accidentally delete the wrong project.

Details

When a user clicks delete

• Open a confirmation modal requesting to type in the project name:

Title: Delete project

Message:  Enter the project name to confirm its deletion. Note: Deleting this project will disable access
for all users, and disable all jobs in the project. {PURGE_DELETED_RECORDS_AFTER_DAYS} days from today, the whole project will be deleted
along with all workflows and work order history.

Input: Project name

Buttons: Cancel, Delete project

• The delete button is greyed out until the user has successfully entered the project name.

Implementation notes

Release notes

• Add confirmation modal to project deletion from projects page

User acceptance criteria

Start at the projects page and trace the existing project deletion flow. Implement the confirmation modal described in the issue, including project-name validation and the warning text; the work is done when the Delete project button remains disabled until the exact project name is entered and Cancel still closes the modal.
