Add redirect stubs for moved/removed pages

- console-and-shells.html → console-commands/
- controllers/components/cookie.html → controllers/request-response.html#setting-cookies

These old URLs return 404 and are still referenced from external
sources. Uses meta refresh for instant client-side redirect with
a fallback link for non-JS environments.
