Add Num{Issues,Pulls} stats checks (go-gitea#21404)

- Backport go-gitea#21404
  - Currently `repository.Num{Issues,Pulls}` weren't checked and could become out-of-consistency. Adds these two checks to `CheckRepoStats`.
  - Fix incorrect SQL query for `repository.NumClosedPulls`, the check should be for `repo_num_pulls`.
  - Reference: https://codeberg.org/Codeberg/Community/issues/696
