Adding, editing or deleting a dish redirected to /ruoat, which stopped
existing when the tab was renamed to Ruuat. Every one of those actions ended
on a 404. Shipped in v20260905-4.
The rename was done with a scripted replace across views.templ, main.go and
the smoke script; handlers.go was not in the list.
The tests did not catch it because they asserted only that the response was a
303. A redirect to a dead URL is still a 303. They now assert the target.
