Use variable for mobile breadcrumbs padding

Closes #38156

See merge request gitlab-org/gitlab-ce!14904

The problem would occur when the `ForkedProjectLink` was deleted, but
the `ForkNetworkMember` was not. The delete would be rolled back and
retried.

But the error would not be saved because `Project#forked?`
would still be true, because the `ForkNetworkMember` exists. But the
`Project#forked_project_link` would be `nil`. So the validation for
the visibility level would fail.

Prevent creating multiple ApplicationSetting by forcing it to always have id=1
