refactor: implement precise login result detection in ERP auth service

Add waitForLoginResult() method with Promise.race to detect three login outcomes:
- Success: detects .nc-workbench-icon element
- Failure: detects '名称或密码错误' error text
- Force login: clicks confirm button and re-detects

Improves login reliability by properly handling all authentication scenarios.
