Stability checkpoint — aligned with svc stable-v1.0.11

UI-side changes since stable-v1.0.10:
- efcffb6 fix(ci): dedupe path filter + add .prettierrc

Modest UI delta — most 2026-04-22 work was svc-side (Phase A closure
+ shield retirement + docs). UI tag posted for cross-repo alignment
so 'stable-v1.0.11' always refers to the same sibling stability
snapshot across both repos.

MR !70 merged via auto-merge. Post-merge main pipeline #326 green.

Backlog (Phase B UI items tracked in svc TASKS.md):
- B-4 CI modularization UI .gitlab-ci.yml 1067 → 6 includes [~2h]
- B-5 quality.component.html 1742 → QualityPanelXxx children [~4h]
- B-6 dashboard.component 1022+1258 → 1 widget/file [~4h]
