fix: desktop nav ignored feature toggles; add chatbots toggle (v0.62.0)

Feature toggles (Settings -> Features) were filtered into
visibleNavItems but the desktop horizontal nav still mapped over the
raw NAV_ITEMS list, so hiding a feature only worked on mobile. Both
nav renders now read the same filtered list.

Also adds a Chatbots toggle covering the recipe cooking-chat panel
and the recipe-list cooking assistant, wired end-to-end (schema,
migration, feature-prefs lib, API route, settings form, i18n,
openapi).
