signals.rs's pass, judge, pace, back_off, check_key and pick_icon ran
only against a live Jev. In cargo tests ask now goes to a stand-in for
it, served from a thread of its own so every test shares it, answering
by key as TypeSafe would: a pass judges each new item once, keeps its
verdicts and bills its owner's tokens on their own key; a refused key
stops its owner's judging, not anyone else's, and is not sent again; a
429 stops the pass and the next call to Jev waits out Retry-After; a
422 stops the pass rather than repeating on every item; a key check
costs tokens; an icon is one Jev was offered, on the server's key.
The API: a Signal made, its words trimmed and deduplicated, bad names,
words, icons and descriptions refused, renamed and re-worded, its icon
cleared, its picked items listed, deleted with its verdicts; someone
else's is 404 every way. In the browser, a Signal renamed and deleted
from its own page. The coverage run runs the browser Signals tests too
(IPX_SIGNALS_TESTS=1): Jev there is the fixture server's.
