Check the token's owner and repository when registering a runner (#30406)

Fix #30378

(cherry picked from commit 0fe9f93eb4c94d55e43b18b9c3cc6d513a34c0b5)

Conflicts:
	- models/organization/org.go
	- services/repository/delete.go
	- services/user/delete.go
	In all three cases, conflicts were resolved by manually adding
        the lines added by the Gitea patch, keeping the Forgejo code
        surrounding them.
