test(12.1): add rendered-flow integration tests and security gate evidence

- Add CloudFolderRenderedFlow.test.js: 7 tests mounting real CloudFolderView with real StorageBrowser/BreadcrumbBar (only API and router stubbed) — mixed root render, opaque-ref folder navigation, breadcrumb lineage, warning freshness cached rows, fresh freshness, XSS text escaping - Update 12.1-VALIDATION.md with Task 3 security gate results: bandit 0 HIGH, npm audit 0 critical, no Phase-12.1 gitleaks findings, 595 backend / 376 frontend tests pass, build clean

+/**
+ * Phase 12.1 Plan 04 Task 3 — CloudFolderView rendered-flow integration test.
+ *
+ * Mounts the real CloudFolderView with the real StorageBrowser and BreadcrumbBar.
+ * Only network boundaries (api/client.js) and router are stubbed. This validates
+ * that the full render path from API response through view → StorageBrowser →
+ * BreadcrumbBar operates correctly with the normalized API shape.
+ *
+ * Scenarios covered:
+ *   1. Mixed root folders/files render through StorageBrowser (not a parallel grid)
+ *   2. Click a folder whose opaque reference contains reserved characters — navigates with
+ *      provider_item_id intact; breadcrumb updated
+ *   3. Navigate back via lineage breadcrumbs — breadcrumb trims to clicked node
+ *   4. Refreshing → warning server freshness state renders with cached rows visible
+ *   5. Fresh server state renders without a warning indicator
+ *
+ * Security constraints (T-12.1-16/17/18/20):
+ *   - No provider credentials, full URLs, or unexpected provider names in test fixtures
+ *   - Provider names appear only as generic stubs; no real Nextcloud/cloud data
