fix(test): replace meaningless assertions with behavior-based tests across 7 test files

Replace toBeDefined()/typeof checks with assertions that verify actual
behavior and output content. Key changes:

- locators: assert actual CSS selector values instead of existence
- logger-integration: test run()/getContext()/withRequestContext() behavior
- logger: verify winstonCalls content (level, message, metadata)
- config-manager: test default values, singleton, and getConfig() throws
- erp-auth: remove empty Class Structure block (covered by behavior tests)
- audit-logger: spy on auditLogger.info to verify JSONL entry content
- extractor: remove Math.ceil tests, verify error result structure

Net: -209 lines of hollow/redundant test code.
