dashboard: the replay window and archive retention in the remake dialog

The remake dialog set the kind, its input, the settle time and the switch delay, but not
the replay window or the archive retention. Now each has two fields, epochs and an age,
their defaults as placeholders: both empty sends nothing (the node's defaults), one
given sends that limit alone, as the API reads it; in the body, or for an import in the
query (`replayWindow`, `archiveRetention`). Epochs that aren't a whole number are
refused in the page.
