fix(test): stabilize waitForEventProcessorShutdown timeout test for CI

- Reduce timeout from 500ms to 200ms to lower CI execution time
- Add 10ms margin to elapsed time check for scheduler variance
- Replace pc.dim() string matching with call count assertion
  to avoid ANSI escape code mismatch on CI runners
