This feature allows admins to find what they are
looking for in the admin interface via a search modal.
This replaces the admin sidebar filter
as the focus of the Ctrl+/ command, but the sidebar
filter can also still be used. Perhaps at some point
we may remove it or change the shortcut.
The search modal presents the following data for filtering:
* A list of all admin pages, the same as the sidebar,
except also showing "third level" pages like
"Email > Skipped"
* All site settings
* Themes
* Components
* Reports
Admins can also filter which types of items are shown in the modal,
for example hiding Settings if they know they are looking for a Page.
In this PR, I also have the following fixes:
* Site setting filters now clear when moving between
filtered site setting pages, previously it was super
sticky from Ember
* Many translations were moved around, instead of being
in various namespaces for the sidebar links and the admin
page titles and descriptions, now everything is under
`admin.config` namespace, this makes it way easier to reuse
this text for pages, search, and sidebar, and if you change it
in one place then it is changed everywhere.

The value field of ThemeField is only used when viewing a diff in the staff action logs and local theme editing. value is being serialized into the theme index as well, which is not used. It's a huge amount of JSON that we can cut by removing it.
This also breaks up the various theme serializers into separate classes so they autoload properly (or at least restart the server on edit)
