Fix some pending problems (#29985)

These changes are quite independent and trivial, so I don't want to open
too many PRs.

* go-gitea/gitea#29882 (comment)
    * the `f.Close` should be called properly
* the error message could be more meaningful
(go-gitea/gitea#29882 (review))
*
go-gitea/gitea#29859 (review)
    * the new translation strings don't take arguments
* go-gitea/gitea#28710 (comment)
    * stale for long time
*  #28140
    * a form was forgotten to be changed to work with backend code
