Content-Transfer-Encoding: 8bit

Pass 3 of M-029 ships per-page render + XSS-hardening test suites for the

14 T-1-deferred pages. Each test:

  - Renders the page with mock data containing <script> payloads in every

    text-rendering field.

  - Asserts no live <script data-xss='...'> element attached to the DOM.

  - Asserts no global side-effect from the script body executed (window

    __xss_pwned__ stays undefined).

  - Asserts the literal payload text appears as escaped content (proving

    the page surfaces the data without rendering it as HTML).

Batch A: 5 simpler pages (display-only / single-mutation / login).

Test files added:

  - DigestPage.test.tsx           preview HTML payload + render coverage

  - LoginPage.test.tsx            useAuth.error payload + form invariants

                                   (mocked AuthProvider via Layout.test pattern)

  - ShortLivedPage.test.tsx       cert subject DN / SAN / id / environment

                                   payloads through the DataTable rendering

  - AuditPage.test.tsx            audit-event action / actor / resource_*

                                   payloads through the DataTable rendering

  - ObservabilityPage.test.tsx    health.status + Prometheus text payloads

                                   through the <pre> rendering surface

Closes 5 of 14 T-1-deferred pages toward M-029 Pass 3 completion.
