## Problem
When creating or editing a dashboard and opening a page layout side
panel (clicking the **"Add widget"** box, or editing a widget via grid
edition), clicking another nav item like **"Opportunities"** crashes the
whole app ("Sorry, something went wrong").
### Steps to reproduce
1. Go to `/objects/dashboards` and click **"+ Add new"** to create a
dashboard.
2. Click the **"Add widget"** box (or add a widget via grid edition and
open its settings).
3. Click another nav item such as **"Opportunities"**.
4. The app crashes.
## Root cause
The side panel stays mounted during its close animation, but the main
context store has already switched to the new page (the record index has
no single targeted record). The still-mounted page layout side panel
page (`SidePanelPageLayoutDashboardWidgetTypeSelect`, chart settings,
etc.) re-renders and calls `usePageLayoutIdFromContextStore`, which
throws `Error: Only one record should be selected`. With no local error
boundary, the throw propagates to the top-level boundary and crashes the
app.
## Fix
`SidePanelRouter` now skips rendering page layout side panel pages
whenever the main context store has no single targeted record — the same
condition `usePageLayoutIdFromContextStore` requires to not throw.
During navigation the panel closes cleanly instead of crashing.
This is safe because `usePageLayoutIdFromContextStore` unconditionally
throws without a single-record selection, so the guard can only skip
pages that would otherwise crash — it cannot break a currently-working
flow. The guard uses the existing `isPageLayoutSidePanelPage` helper, so
it covers all page layout side panel pages (widget type select, chart /
iframe / record table settings, record page field settings, etc.).
## Testing
- Reproduced the crash in the running app, applied the fix, and
confirmed navigating to Opportunities from both the **widget type
select** and the **chart settings** panels now lands on the
Opportunities list with no console or page errors.
- `oxlint --type-aware` and `nx typecheck twenty-front` both pass.
