Varaverk: suggested cron hints left of every cron input

- vv_script_children() now calls vv_script_suggested_cron() per child,
  adding suggested_cron and suggested_label to each child entry
- Orch rows (non-event) and regular script child rows render a faint
  .vv-cron-hint span to the left of the cron input showing the suggested
  cron from the script's # Schedule: header
- Clicking the hint fills in the cron input (data-cron + onclick)
- Tooltip shows full "suggested_cron — label" string on hover
- .vv-cron-hint: color #444, brightens to #888 on hover
