// New Project and Edit Project (agent/modals/project/project_form.php):
// the client contact picker follows the client picked, and an internal
// project has none; "assign the template's tickets" shows once a template
// is picked; the due date can't be before the start.
//
// Wrapped in an IIFE because a modal can be opened, closed and opened again
// in one page load, which re-runs this file.
