test(cli): extend tests for environment, sdk, and alerts utilities

- Extend environment.test.mts with detectAndValidatePackageEnvironment tests
- Extend sdk.test.mts with tests for URL/proxy/token getters and setupSdk
- Extend alerts.test.mts with comprehensive coverage for getAlertsMapFromPurls
- Fix import path issues (5 levels -> 4 levels)
