Add test for the job page when the available runners for the job are all
offline.

Removes isJobStuck check from frontend and uses
the flag being provided by the API

Frontend currently defines when a job is stuck, which we already have in
the backend, expose `stuck` field in the
`Project::JobsController#show.json` so the duplication of the logic is
removed.

[EE-Port] Remove ForkedProjectLink model

This removes the `ForkedProjectLink` model that has been replaced by
the `ForkNetworkMember` and `ForkNetwork` combination. All existing
relations have been adjusted to use these new models.

The `forked_project_link` table has been dropped.

The "Forks" count on the admin dashboard has been updated to count all
`ForkNetworkMember` rows and deduct the number of `ForkNetwork`
rows. This is because now the "root-project" of a fork network also
has a `ForkNetworkMember` row. This count could become inaccurate when
the root of a fork network is deleted.
