Summary

Brief description of what this PR does.

This PR adds end-to-end (E2E) test coverage for key B2C CLI workflows using real CLI commands and real sandbox infrastructure.

What’s covered

• Auth & Tokens
  Token generation, default/custom scopes, and basic failure cases

• ODS Lifecycle
  Create, list, deploy, check status, stop/start/restart, and delete sandboxes
  Includes basic error and auth scenarios

• Jobs
  Run jobs, wait for completion, search executions, and import/export flows

• Sites
  List sites, import site archives, sequential imports, and graceful failures

• SLAS
  Client create, list, get, update, delete, plus invalid input cases

• WebDAV
  Upload/download/delete files, directory operations, zip/unzip flows

Test approach

• These are true E2E tests no mocks, real APIs, real sandboxes
• Tests assert CLI JSON output and observable side effects
• Tests are gated by environment variables so they don’t run with unit tests
• A shared sandbox is used when available so multiple E2E suites can run against the same environment, reducing sandbox creation time and cost
• Tests automatically fall back to creating their own sandbox when shared mode isn’t enabled

Testing

• Tests pass (pnpm test)
• Code is formatted (pnpm run format)
