Relocate GitLab Duo Self-Hosted Pages to Main Duo Settings Page

What does this MR do and why?

As part of efforts to unify AI settings UX, the GitLab Duo Self-Hosted pages are being relocated to link out from the main Duo settings page (/admin/gitlab_duo) and the current stand-alone menu item in the admin menu is to be removed.

See Figma design

Out of scope:

• Routing updates are to be tackled in a follow up piece of work

How to set up and validate locally

Pre-requisites

• You will need an active Ultimate online cloud license.
• Make sure you are set up with a Duo Enterprise subscription by running the following command in the terminal:

GITLAB_SIMULATE_SAAS=0 bundle exec 'rake gitlab:duo:setup[duo_enterprise]'

1. Start GDK in self-managed mode (GITLAB_SIMULATE_SAAS=0 gdk start)
2. Navigate to http://gdk.test:3000/rails/features/ and enable the ai_duo_chat_sub_features_settings feature flag
3. Visit Admin Area > GitLab Duo
4. Find the "Configure AI Features" info card and click the "Configure Self-hosted models" button. This should navigate to the GitLab Duo Self-Hosted pages. Validate the pages are all working as expected and that there is a GitLab Duo breadcrumb which leads back to the Duo settings page.
