Add Instance Security Dashboard component

See merge request gitlab-org/gitlab!16496

This implements the basic scaffolding of the root application component
that wraps the security dashboard, and leaves a placeholder for the
project selector.

Another MR will implement the project selector, and likely a third will
integrate the two into the store.

Part of the [Instance Security Dashboard MVC][1].

Resolve "Remove Security Dashboard router from pipelines view"

See merge request gitlab-org/gitlab!17767

This reduces a bit the coupling of the security dashboard's router and
store, and [removes the router from the Pipeline Security Dashboard][1].

Now, to sync a security dashboard to its router (as is done for the
Group and Project Security Dashboards), the router must be explictly
created and bound to the store using the `syncWithRouter` store plugin
at store creation.

Create table and model for Grafana integration

See merge request gitlab-org/gitlab!17234

In preparation for supporting the ability to embed Grafana metrics
in GitLab Flavored Markdown, we need to allow a way for users to
store credentials for us to access the HTTP API for their grafana
instance. We expect users to save two key attributes:
an authorization token and the url of their grafana instance.

This work adds the table and model for storing this auth config.
