M-029 Pass 3 batch B: T-1 tests for 4 detail pages — XSS hardening

Continues Pass 3. Each detail page has its own narrow attack surface

(subject DN, last_test_message, error_message) that the test exercises

with literal <script> payloads in every text field.

Test files added:

  - CertificateDetailPage.test.tsx  cert subject / SANs / serial / PEM

                                     across 7 sidecar queries (getCertificate,

                                     getCertificateVersions, getTargets,

                                     getProfile, getProfiles, getRenewalPolicies,

                                     getJobs all mocked in beforeEach)

  - IssuerDetailPage.test.tsx       issuer name / type / config / last_test_message

                                     (router-aware test using Routes + useParams)

  - TargetDetailPage.test.tsx       target name / config / last_test_message

                                     (router-aware test pattern)

  - JobDetailPage.test.tsx          job error_message / type / details

                                     (3-query mock: getJob + getJobVerification +

                                     getAuditEvents)

Closes 9 of 14 T-1-deferred pages toward M-029 Pass 3 completion (5 batch A,

+ 4 batch B = 9; 5 to go in batch C).
