M-029 Pass 3 batch C (FINAL): T-1 tests for 5 list pages — Pass 3 complete

Closes M-029 Pass 3 fully. Every src/pages/*.tsx now has a *.test.tsx peer.

Audit recon: 'comm -23 <pages> <test-peers>' returns zero (all 14 T-1-deferred

pages now covered).

Test files added (each ships render-coverage + an XSS-hardening contract):

  - HealthMonitorPage.test.tsx     endpoint URL + last_error payloads

  - JobsPage.test.tsx              type / certificate_id / agent_id /

                                    error_message payloads

  - NetworkScanPage.test.tsx       network_range / agent_id / last_scan_message

                                    payloads

  - ProfilesPage.test.tsx          profile name / description / EKUs payloads

  - AgentFleetPage.test.tsx        agent name / hostname / OS / arch / IP

                                    payloads (mirrors the M-003 MCP fence shape)

Pass 3 totals across batches A + B + C: 14 new test files, 14/14 T-1-deferred

pages closed. Each test pins three invariants:

  1. The page renders against mock data without crashing.

  2. No live <script data-xss='...'> attaches to the DOM.

  3. The literal payload appears as escaped text content (proving the page

     surfaces the data without rendering it as HTML).

M-029 status after Pass 3:

  Pass 1 — useMutation -> useTrackedMutation     COMPLETE (6 batches, 56 -> 0)

  Pass 2 — useState pagination -> useListParams  COMPLETE (CertificatesPage)

  Pass 3 — XSS-hardening test suites             COMPLETE (14/14 pages)

M-029 IS NOW READY TO CLOSE.
