refactor: Improve service startup and management logic

- Add `create: true` to service `get` calls
- Update `running_check` to use `curl` for HTTP status code
- Ensure redis addresses have `redis://` prefix
- Clean up and re-create zinit services before starting
- Remove redundant `service_monitor` call in `startupmanager.start`
