fix!: mark Document.Entity.type as REQUIRED in all versions (#326)

* fix!: mark Document.Entity.type as REQUIRED in all versions
fix!: remove Document.Entity.bounding_poly_for_demo_frontend from v1beta2

The type field was always required by the backend, so this formally breaking change can likely be accepted without bumping the major version. Field removal is in beta version so can be accepted as well.
