fix: docker compose pids location + clear stale update banner

- Move pids limit from service-level `pids_limit` to
  `deploy.resources.limits.pids` for Compose v5+ compatibility.
  Some Compose versions normalize both into the same field, causing
  "can't set distinct values" errors.

- Clear OpenClaw update banner when `/api/openclaw/version` reports
  `updateAvailable: false`. Previously the banner could persist after
  a successful update because only the `true` path was handled.

Closes #353, closes #351
