The domain column showed a dash unless a hive had a dashboard but sorted
and filtered on the domain alone, so rows looked mis-sorted. It now shows
the domain as text when there is no dashboard to link. An empty hive
roster says so. The schedule form's agent names reload with the schedules
and the form says when that load failed.
A start in the past fires the latest missed time once, right away, so the
form says that instead of 'already passed'. A one-shot past its time reads
'past' / 'time passed' (the controller's clock, not a record of firing) and
keeps its pause button. The edit form compares against what it opened with,
so a schedule changing under it is not reverted on save.
/schedules lists the controller's scheduled prompts as cards: name as the
title, the agents it fires for, the message, its cadence and next fire.
Edit turns a card into its own form; pause, resume and remove act in place,
and + schedule opens an empty form. The form sends only what changed, so a
rename never moves the fire times, and warns when the start or the repeat
does. Filters reuse the shared card filter bar.
Adds a TextAreaField to the ui kit, and an upcoming mode on RelativeTime so
a next-fire time reads "in 5m". Needs the controller's /api/schedules
routes.
