Set the owed mesh/check through gitea_check_status, the one tool that writes it (issue 1301's delivery part, option A)

The forge's gitea_commit_status refuses the context mesh/check from R4e, so that only the checker's account, through
this bridge, can make a pull request pass the one required status.
