Maurice 00cbc5aae3 test(server): src/config takes fixed test values from the setup file, so suites stop mocking it
tests/setup.ts mocks src/config once with tests/helpers/test-config.ts. A suite that needs other values calls overrideTestConfig(), and the setup file restores the defaults after every case. The 191 per-file factories are gone; config.test.ts takes the real module through vi.unmock, and the few suites that signed tokens with their own literal secret read it from TEST_CONFIG.
