Show Candidate Email in Profile.

REQUEST

Hi. In the candidate detail drawer, display the candidate’s email address beneath their title and company. Make it a clickable mailto: link and add an automated test for it. Do not change the database schema or migrate any data.

APPROVED PLAN

1. User-visible behavior

- In the candidate detail drawer, show the candidate’s email beneath the title/company line.
- Render it as a clickable link with `href="mailto:<candidate email>"`.

2. Frontend changes

- Update the drawer markup in `components/recruiting-app.tsx`.
- Add a styled email link beneath the existing title/company text.
- Preserve the existing candidate editing and recruiting workflows.

3. Backend and Convex changes

- None required. Candidate email already flows through:
  - Convex schema and candidate mutations
  - Dashboard query
  - API validation
  - Shared `Candidate` type
  - Demo data fallback

4. Migration assessment

- No stored-data change is needed, so no app-version bump, migration entry, or `.factory/schema.transition.ts` file should be added.
- Existing records already contain email addresses; no transient widened schema, backup/stash, forward transform, rollback, reapply, or row-count/invariant migration work is required.
- The existing factory migration contract should remain unchanged and continue validating its current data lifecycle if invoked by the preview harness.

5. Tests and browser verification

- Extend `e2e/factory-preview.spec.ts` after opening an existing candidate drawer.
- Assert the email is visible and the link has the expected `mailto:` href, e.g. Ava Chen’s email.
- Run the repository contract commands: typecheck, unit tests, build, and Playwright/browser verification.

6. Risks or questions

- No material safety blockers identified. The request is isolated to presentation and can be implemented safely in an isolated preview without schema or data migration.
