fix: add Playwright, Valkey, and mock-OIDC to CI pipelines

- Add valkey and mock-oidc services to both release and dev workflows
- Install Playwright with Chromium deps for headless e2e tests
- Set WG_REDIS_URL and MOCK_OIDC_HOST env vars for CI
- Make mock OIDC discovery URL configurable via MOCK_OIDC_HOST env var
- Add full test job (unit + e2e) to dev pipeline before Docker build
