Add bot schedules (routines), open Activity, add Help and a Desktop computer view

Bots create, list, update and delete schedules (cron_jobs, Bun.cron in UTC);
a per-minute cron queues due runs as tasks. Routines, Activity (super admins)
and Help get their own rail aside. Help covers familiar problems, starting
with signing in to Google through Cookie-Editor over the new Desktop (noVNC)
view.
