🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR reverts the selector change introduced in #498, restoring the getByRole("menuitem", { name: "self-hosted" }) lookup in fixtures/extension-setup.ts. The reverted-to selector is semantic and consistent with existing patterns in the codebase (e.g., tests/a11y/web-client.spec.ts:48). The removed #cdk-overlay-0 selector relied on a sequentially generated Angular CDK ID, which is fragile if other overlays render first. The change is minimal and isolated; no code-level findings.

• ❓ QUESTION: The PR description is the default "This reverts commit ..." message and omits the project's PR template sections (Tracking, Objective). Since this revert undoes a fix targeting BIT configuration, please add context on why the revert is needed (e.g., is the original selector failing somewhere, is a different fix planned?) so future readers and reviewers understand the intent.
