{# Schedule- and vendor-aware behaviour shared by the job forms (job page, clone, add-job):
   - daily: show "Expected by"/"Grace hours", hide the interval window block
   - any interval: hide the daily fields, open the interval block, and prefill
     grace = interval/2 (30 min -> 15, hourly -> 30, 2-hourly -> 60, ...) — still editable.
   - vendor hints: picking CloudAlly snaps the schedule to daily (it's one summary email per
     account per day), prefills an empty name, and shows a how-it-matches note.

   The "Run on" weekday checkboxes carry NO data-sched marker in any form, so this toggle never
   hides them: parsers.evaluate_missed applies the selected days to daily schedules as well as
   intervals, and burying them in the interval block made a weekday-only or weekly daily job
   effectively unconfigurable. Anything that must follow the frequency keeps its marker;
   the weekday fieldset must stay outside both. #}
