fix: match working OpenEnv space configuration exactly

- Restore base_path: /web in README (required by all working OpenEnv spaces)
- Switch HEALTHCHECK from curl to python urllib (curl not in openenv-base)
- Increase start-period from 5s to 30s
- Remove root redirect hack (base_path handles this)
- Keep PYTHONUNBUFFERED=1 and ENABLE_WEB_INTERFACE=true
