fix(config): add event.subscribe.enable config key and remove incorrect --fast-forward mapping

- Add event.subscribe.enable as config equivalent for deprecated --es CLI flag
- Remove --fast-forward from CLI-to-config mapping (no config equivalent;
  fast-forward is a node runtime mode, not a config option)
- Config reads event.subscribe.enable with CLI --es taking priority
