feat: A20 phase 3 LOT 1 — shell + library migres, harnais csp_preview vert (v7.38.0)

Ajout :
- e2e/csp_preview.spec.js — apercu CSP strict SANS deployer : le build
  officiel @alpinejs/csp (e2e/fixtures/alpine.csp.js, 0 eval) est servi a
  la place de alpine.min.js par interception Playwright ; toute expression
  que le parseur maison ne digere pas = pageerror (filet). Premiere
  surface VERTE : library (composant lie, icones SVG via Alpine.effect,
  recherche ouverte + focalisee, 0 erreur).

Changed :
- 16 composants x-data="fn()" enregistres via Alpine.data (registre =
  seule resolution du build CSP, probe « Undefined variable » ;
  scripts classiques executes pendant le parsing => alpine:init toujours
  joint) : appState, libraryPage, workspacesPage, editorState, board x4,
  settings/import/table_view/team_load/trash/workspace/welcome/accounts/
  card_detail.
- base.html (shell) migre : x-effect document.* -> syncSidebarClass(),
  $nextTick(arrow) -> initSidebarSort(), window.FlowDeck.* ->
  fdCreatePage/fdCreateFolder/fdGwRefresh, Object.keys/Math.min/
  window.innerWidth dans x-for et :style -> sidebarSections()/
  sectionMenuPos() — tout = simple appel de methode.
- x-html restants du shell -> x-init + Alpine.effect : icone agent,
  carte projet, library x3 ; recherche library -> toggleSearch()
  (Alpine.nextTick) ; openMoveSelected() pour Object.keys en expression.
- eslint : 70 warnings -> 0/0 (globals getCsrf depuis A38 ph1,
  /* exported openCardDetail */ + /* global owner, repo */, 3 ;; residuels).

suite **1093/1093** · ruff OK · eslint 0/0 · E2E 3/3 (csp_preview + smoke x2)
