fix port 8000->7860 in app.py/openenv.yaml, add pyproject script entry, fix stubs

- server/app.py: fix __main__ port 8000 -> 7860, extract main() fn, reload=False
- openenv.yaml: add app_port: 7860
- pyproject.toml: add [project.scripts] server entry point
- tests/openenv_test_stubs.py: add done/reward/metadata to Observation stub,
episode_id/step_count to State stub so integration tests work correctly
