test: microservice coverage for task 63

Add table-driven HTTP and unit tests for report (all formats, negatives),
upload/auth boundaries, upload helpers, readiness, Run and logging.
Extend authkeys tests for Close, CreateKey validation, and post-close errors.
Add CLI tests for defaultListenFromEnv and create-client-key with -auth-db only.
Add mage CoverMicroservice for local/CI-style coverage measurement.
Use context.Background and os.Chdir for Go 1.21-compatible tests.
