Preserve the selected project scope on project pages.

/projects/$projectKey redirects to /settings/projects?project=$projectKey, where the settings scope represents the selected project group and optional environment. NewThreadShortcuts ignores that scope. With no active thread or draft, chat.newLocal uses the global defaultProjectRef, and chat.newWithoutProject uses the primary environment. For a selected project outside that default context, the shortcuts can target the wrong project or environment.

Resolve the settings scope to the appropriate project member and environment before invoking these actions. Handle grouped projects explicitly because one project key can represent multiple environment members.

- 232:
Update the NewThreadShortcuts flow in AppSidebarLayout around useHandleNewThread
to resolve the settings project scope to the correct project member and optional
environment before invoking chat.newLocal or chat.newWithoutProject. Handle
grouped projects explicitly so shortcuts preserve the selected project and
environment instead of falling back to the global default project or primary
environment.
