fix(e2e): activate e2e profile in dev mode and create reader user idempotently

- Add e2e to the dev Maven profile's spring.profiles.active so
  DataInitializer always runs when developing/testing locally
- Create the reader test user independently of the person-seed guard
  so it survives restarts where seed data already exists
- Set SPRING_PROFILES_ACTIVE=dev,e2e in docker-compose backend service
