Let the search reach past the twentieth of a kind, and unbreak two specs

The global search capped each category before cmdk had matched anything, so
nothing past the twentieth node or widget could be found at all — this
instance has 28 nodes and 97 widgets. The cap now trims the candidates the
query could reach rather than the raw index.

The admin teardown asked /users/ for limit=1000, which the route stopped
accepting when its bounds went in; a 422 body has no `data` to iterate, so the
hook threw and took the tests it was attributed to with it. It asks for the
500 the route allows.

And `submit` folds every declared initial into a run's params, so an input the
run never passed can no longer read as the flow's own. That assertion is gone;
what the panel does show — the value the run actually started from, passed or
not — is what the test checks.
