merge: resolve main conflict — conserve board smoke (PR #13) + dossier smoke (PR #14)

Conflict: CHANGELOG.md (add/add) and package.json (v1.1.0 vs v1.2.0).

Resolution:
- CHANGELOG.md: keep both entries, v1.2.0 above v1.1.0 (chronological order).
  Updated v1.2.0 description to reference v0.19.2 / v0.19.3 (hotfix context).
- package.json: use version 1.2.0 (PR #14 head; dossier smoke is the newer addition).
- tests/03-admin-plugins.spec.ts: auto-merged by git — board describe block (PR #13)
  at line 97, dossier describe block (PR #14) at line 158. Both conserved.

Dossier smoke selector #prab-dossier verified against v0.19.3 template
(templates/admin/dossier-page.php line 62/86) — registration parent change
does not affect markup.
