This commit changes how we eager-load projects, routes, and namespaces
required by the deploy keys endpoint, getting a 10x improvement in my
local testing.

The endpoint still doesn't scale in-general, but going from ~13 seconds
to dump a 63K result to generating the same thing in ~1.6 seconds seems
like a good improvement to me.

This whitelists all existing offenses for the various CodeReuse cops, of
which most are triggered by the CodeReuse/ActiveRecord cop.

Enable frozen string in:

* app/presenters
* app/policies

Partially addresses #47424.

We use controller actions to pass a newly created token and errors

Also:
- Changes scopes from serializer to use boolean columns
- Fixes broken specs

- Remove extra method for authorize_admin_project
- Ensure project presence
- Rename 'read_repo' to 'read_repository' to be more verbose

Also fixes spec failures on presenter and docs

- Keep 'Deploy Section' open upon save, otherwise the token might get
  lost
- When an error appears, display the error inside the form and also keep
  the Deploy Section open
- Changue copy of revoke modal

Includes:
- Model, factories, create service and controller actions
- As usual, includes specs for everything
- Builds UI (copy from PAT)
- Add revoke action

Closes #31591
