fix(e2e): get all E2E tests passing and fix AlertDialog crash on delete

- Fix rate limiter to allow 100 attempts in dev mode so E2E tests are
  not blocked by failed-login attempts during test development
- Simplify logout button selector to use Lucide icon class (lucide-log-out)
  instead of the fragile Tooltip-content locator chain that broke on navigation
- Rewrite stacks E2E spec: use waitForFunction to wait for sidebar to load,
  delete leftover stacks via browser-context fetch before creating, and use
  page.reload() to get a clean sidebar state
- Fix AlertDialogContent: remove asChild+motion.div pattern that triggered a
  React.Children.only crash — Radix AlertDialog.Content injects a second
  DescriptionWarning child internally, breaking Slot when asChild=true; replace
  with CSS keyframe animations (data-[state=open]:animate-in)
- Fix final assertion in delete test to use exact text + listbox scope to avoid
  false positives from similarly-named stacks like e2e-test-stack-*
- All 6 E2E tests pass (4 auth + 2 stacks); node tests skip gracefully

 ### Fixed
 - **Fixed:** Four empty `catch {}` blocks in `EditorLayout` (mark-all-read, delete notification, clear-all notifications, image update fetch) now surface errors via `toast.error()` instead of silently swallowing them.
 - **Fixed:** `ErrorBoundary` component existed but was not connected — it now wraps the root `<App />` in `main.tsx`, catching crashes in any context provider or route component.
+- **Fixed:** `AlertDialogContent` used `asChild` on `AlertDialogPrimitive.Content` with a `motion.div` wrapper — Radix internally injects a second child (`DescriptionWarning`), causing `React.Children.only` to throw and the ErrorBoundary to trigger whenever the delete-stack confirmation dialog opened. Replaced with CSS keyframe animations (`data-[state=open]:animate-in` / `data-[state=closed]:animate-out`) which don't require `asChild`.
 - **Fixed:** `WebSocket.Server` replaced with named import `WebSocketServer` from `ws` to fix ESM/CJS interop in test environments.
 - **Added:** Cross-node notification aggregation — the notification bell now surfaces alerts from all connected remote nodes, not just the local instance. On mount and whenever the node list changes, `EditorLayout` fetches notification history from every registered node in parallel (using `fetchForNode` with targeted `x-node-id` headers). Each remote node also gets a dedicated real-time WebSocket connection (`/ws/notifications?nodeId=`) so alerts push instantly as they fire. Remote-sourced notifications display a node-name badge for quick identification. Mark-as-read, delete, and clear-all actions are routed to the correct node. The backend WS upgrade handler was updated to allow `/ws/notifications?nodeId=<remoteId>` to fall through to the existing proxy path (bare `/ws/notifications` with no nodeId continues to connect locally as before).
 - **Fixed:** Remote node host console and container exec WebSocket connections now succeed — the gateway exchanges the long-lived `node_proxy` api_token for a short-lived `console_session` JWT (60 s TTL) via a new `POST /api/system/console-token` endpoint before forwarding the WS upgrade to the remote. Previously the remote's `isProxyToken` guard correctly blocked `node_proxy` tokens from interactive terminals, which also blocked legitimate user-initiated console sessions routed through the gateway.
