Fix: DataInitializer re-runs on every restart crashing the app - #18

DataInitializer had no guard against running on subsequent container restarts. On redeployment, duplicate inserts hit the unique constraint on admin/student emails, throwing DataIntegrityViolationException and preventing the app from starting -- causing Azure to keep serving the old container. Added an early-return check so seeding only happens once on a fresh database. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
