Close and reopen refuse what no reader would count

pull close, pull reopen, issue close and issue reopen (and their MCP tools and the pages' buttons) used to write a state record for any URI and say it worked, even for an issue that does not exist, such as one named under the wrong account, or for someone who may not change it. Readers ignored those records, so nothing changed but a stray record in your account. Now they read the item first, and refuse one that is not there, a caller who is not its author, the owner or a collaborator, a merged pull (pull revert undoes one), and a state it is in already.
