test: unit tests for pure provider/config/auth packages

First increment toward 90% core-package coverage. Adds Docker-free unit tests taking these packages to full or near-full coverage: - provider/npm, provider/alpine, provider/puppet: 100% - provider/pypi: index generation via a fake FileStore, upload validation, name parsing, classification, rewrite - config: defaults, overrides, DSN, invalid port - auth: basic header with/without credentials Infra-backed packages (database, storage, cache, proxy engine, api handlers, server) still need the testcontainers batch to reach 90%.
