fix: keep AI chat open when opening a record full-page (e.g. workflows) (#22036)

## Problem

When the AI chat is open in the side panel and you click a workflow from
the Workflows list, the AI chat closes as you navigate to the workflow
page. Navigating between other index/list pages, or to settings, keeps
the chat open — only opening a record full-page closes it.

## Root cause

`useOpenRecordFromIndexView` unconditionally calls
`closeSidePanelMenu()` before navigating to a full-page record:

```ts
} else {
  closeSidePanelMenu();
  navigate(AppPath.RecordShowPage, { ... });
}
```

Workflows (and other objects excluded by `canOpenObjectInSidePanel` —
`workflow`, `workflowVersion`, `dashboard`) can't open in the side
panel, so they *always* take this branch and close the panel, including
the AI chat.

This is inconsistent with `PageChangeEffect`, which already lets the AI
chat survive navigation by exempting `SidePanelPages.AskAI`. That
exemption is why navigating between index pages or to settings doesn't
close the chat.

## Fix

Skip the close when the side panel is showing the AI chat, mirroring the
exemption already used in `PageChangeEffect`. Any other side panel page
still closes as before.

## Testing

- `nx lint:diff-with-main twenty-front` (file lints clean)
- `nx typecheck twenty-front` passes
