Optimise UpdateBuildQueueService

Closes #66438

See merge request gitlab-org/gitlab-ce!32095

Root namespaces have storage statistics.
This commit allows namespace owners to get those stats via GraphQL
queries like the following one

{
  namespace(fullPath: "a_namespace_path") {
    rootStorageStatistics {
      storageSize
      repositorySize
      lfsObjectsSize
      buildArtifactsSize
      packagesSize
      wikiSize
    }
  }
}

Prefer the deployable user over the deployment user.

Related to https://gitlab.com/gitlab-org/gitlab-ce/issues/66037.

This makes BuildQueueService to force refresh runners
that are considered to have recent queue.

Such runners are the ones that connected within online
interval + time to expire runner cache.

This commits avoiding conflicts between ArchiveTraceWorker
and ArchiveTracesCronWorker by changing the target of the
latter worker.

Adding, destroying and toggling emoji previously lacked services and
instead were performed through methods called on Awardable models.

This led to inconsistencies where relevant todos would be marked as done
only when emoji were awarded through our controllers, but not through
the API. Todos could also be marked as done when an emoji was being
removed.

Behaviour changes

- Awarding emoji through the API will now mark a relevant Todo as done
- Toggling an emoji off (destroying it) through our controllers will no
  longer mark a relevant Todo as done
