fix: A27 phase 2a — éditeur 2 516 L extrait via page-data JSON (v7.22.0)

- `_page_editor_scripts.html` : le gros bloc interpolé (2 516 L) part vers
  `static/js/page_editor_scripts.js` — recette « config JSON » : les 8
  interpolations Jinja lisent `PD = JSON.parse(#page-data)`, bloc JSON qui
  EXISTAIT DÉJÀ juste avant le script (même ordre d'exécution), garde
  `__fdEditorScriptsLoaded` préservée, node --check vert.
- Route `view_page_root` : page_data enrichi de updated_at, created_at,
  user_id, is_shared (dérivé HOISTÉ : une seule expression sert le ctx ET le
  JSON) et clip_icon (macro fd_icon rendue côté serveur). workspace_key reste
  vide comme avant (jamais défini dans ce ctx → parité stricte).

8 tests adaptés à l'extraction (ils lisaient le template SOURCE) :
- test_ai_writing ×2 (+ helper _read_js), test_pwa_offline,
  test_v511 front_end_wired, test_v55 ×3 → lisent le JS extrait
- test_page_editor_renders_page_is_shared → parsing du JSON #page-data
  (`is_shared is True`) — la valeur sert toujours à la page

Cumul A27 : 6 759 L extraites (13 904 → 7 145 inline). Reste : local_workspace
2 031, base 1 523 (structurel {% for %}/{% block %}), database_table 1 323,
settings 1 093, realtime 531, board 146 ≈ 6 653 L + 120 warnings eslint.
