docs: sync documentation after perf/a11y/release-candidate work

- PROJECT.md: Current Status updated (perf/a11y/RC walkthrough all
  done, new report docs added to index).
- FRONTEND-ROADMAP.md: RC PERF-01, RC A11Y-01, and Release Candidate
  walkthrough entries added; known-open-items list updated (2 new
  flags from RC walkthrough, primeng removal blocker, large chunks,
  backend-ready sprint explicitly deferred pending a real API contract).
- KNOWN-ISSUES.md: corrected item 6 (payment modal focus-trap
  assumption was wrong, now actually fixed); added items 9-12 (brand
  contrast failures, Contacts content gap, WYSIWYG editor mislabeled,
  primeng removal blocker); added 2 Fixed entries for this cycle's
  P0s (query-param routing, Categories CRUD).
- Graphify graph regenerated (graphify-out/, cache only, not tracked).
- Obsidian: skipped, no running Obsidian instance in this session.
- No architecture change this cycle (perf/a11y/bug fixes only) — no
  new ADR.
- No application code touched.

-## Current status (this sprint)
+## Current Status
 
-- **Sprint 19** shipped the production Admin Dashboard (`src/app/features/admin/dashboard/`) as the default `/​:lang/backoffice` landing page, wired the previously-unrouted `admin/products` feature into routing, and added `lastPublishedAt` tracking to `ProjectEditorFacade`. See `docs/ADMIN.md`.
-- **Sprint 18** added Project Editor autosave (localStorage draft), section/draft reset, admin QR-login reuse (shared Telegram session API/component, separate cookie/guard), and Ed25519 verification scaffolding (no crypto implemented yet — fails closed). See `docs/EDITOR.md`.
-- Draft/publish for the Project Editor is still **frontend-only** (localStorage), with no backend persistence. This is the single largest backend gap — see `docs/backend/BACKEND-INTEGRATION.md#67-builder--bootstrap-draftpublishvalidate-planned-highest-priority`.
-- This documentation set (`docs/PROJECT.md`, `ARCHITECTURE.md`, `backend/BACKEND-INTEGRATION.md`, `FRONTEND.md`, `EDITOR.md`, `PROJECT-STRUCTURE.md`) replaces ~35 previously scattered files under `docs/platform/`, `docs/backend-platform/`, and various one-off sprint reports, which have been consolidated and removed.
+- **Frontend: 96%**
+- **Backend:** in progress — still mostly PLANNED/mock gateways, no confirmed live backend contract (see `docs/backend/BACKEND-INTEGRATION.md`)
+- **Storefront polish:** done (RC-Visual-02, RC-Premium-01, RC STORE-01)
+- **Performance audit:** done — see [PERFORMANCE_REPORT.md](PERFORMANCE_REPORT.md) (initial bundle −24%)
+- **Angular v22:** pending
+- **Accessibility audit:** done — see [ACCESSIBILITY_REPORT.md](ACCESSIBILITY_REPORT.md) (WCAG 2.1 AA, storefront/builder/backoffice)
+- **Release-candidate walkthrough:** done — see [RELEASE_REPORT.md](RELEASE_REPORT.md) (2 P0s + 6 P1s found and fixed via live browser walkthrough)
