fix(help-config): non-destructive info open, clean cancel, drop dead config

Three audit defects in one file. cj/open-with-info-mode used cl-return-from inside a plain defun, so declining the save prompt threw "No catch for tag" instead of cancelling. The decision is now a pure cj/--info-open-plan and the command routes through it. A dead :hook (info-mode . info-persist-history-mode, which names a non-existent mode on the wrong hook) and an empty :preface are gone. The auto-mode-alist entry that mapped .info to that interactive, buffer-killing command is dropped, so find-file-noselect of a .info no longer destroys buffers. cj/open-with-info-mode stays an M-x command and C-h i still browses info files.
