Wire real autosave into translation editing

The shared TinyMCE setup initializes cccms.setup_autosave() on any
page with a textarea.with_editor, unconditionally starting a
7-second interval that submits to the form's data-autosave-url --
which the translation edit form never set, so the interval PUT the
current page URL itself and 404'd on a nonexistent route.

Fixed by actually giving it something to talk to, rather than
suppressing it: a real autosave endpoint, and update now goes
through Node#autosave!/#save_draft! -- the same pipeline the
primary editor uses, fixed earlier this session for exactly this
kind of cross-locale carryover. This was the autosave-buffer parity
already flagged as due after the proof of concept; the shared JS
just forced the timing.
