fix(e2e): seed project in empty-tasks overview test

With truncateAll wiping all tables, the test user has no projects,
so ShowTasks never renders and tasksLoaded stays false — meaning
ImportHint (which is gated on tasksLoaded) never appears. Seed a
project with default views so the empty-state hint is visible.
