New run: start a run from the app, on the working copy

The site promises simulated inputs and mocked sensor values, and nothing in
the app was that. A run already is: the values are the caller's, the state is
the run's own namespace, and nothing it computes reaches the live flow. What
was missing was a screen to do it from, and the draft flag being honoured.

`/runs/new` is a flow, a field per declared input, a seed and Run; `/runs`
stays the log. A comma-separated list in a number field expands into the grid
`fluksio sweep --param` builds and goes to the sweep route, so launching one
no longer needs a terminal. Only numbers split: a comma in a string is
content, and one in JSON is syntax.

`RunCreate.draft` was validated at submit and dropped before the run
executed, so "try the working copy" ran the published one. `Run.draft` is a
column now, the driver reads the same copy the submit checked, and a retry
carries it. `FlowSummary.mode` came with it so the rail can say which flows
are batch before one is picked.

Also here: a Retry button on a finished run, which the route has always had
and the UI never did, and parameter cells truncated to their column with the
full value on hover.
