fix(cookbook): point HF token hint at Cookbook -> Settings, not Settings -> Cookbook (#3864)

The 'HF token: NOT SET' shell hint shown when downloading a gated/private
model told users to add a token under 'Odysseus Settings -> Cookbook ->
HuggingFace Token'. There is no Cookbook section under the app Settings;
the HuggingFace Token field lives under the Cookbook page's Settings tab
(static/js/cookbook.js — data-backend="Settings" group). Following the
old hint led nowhere. Reverse the path to match the real UI.

Fixes #3829
