fix: stop spinner before error propagates, show PM2 logs on health check failure

- Stop spinner explicitly on deploy error so ui.error output is visible
- Add 2s delay between health check retries
- Fetch last 30 lines of PM2 logs when health check fails so the user
  can see why the app didn't start without running a separate command
