Fix namespace issue preventing Ci::Build filtering optimization

The performance optimization introduced in !190206 (merged) is not being executed due to an incorrect model namespace resulting from mid-review refactoring.

This commit corrects the namespace to ensure Ci::Build entries are properly filtered, restoring the intended runtime reduction for the rake task on large installations.

Changelog: fixed

Testing

On a single node Omnibus install with 50k Ci::Builds with a niled token:

  • Omnibus GitLab 18.2.1 (unpatched): 9m30s
  • patched: 57s

This matches the results we saw/expected in !190206 (merged).
