feat: forward repeat through cron.manage add (#85602)

cronjob(action=create) has supported a repeat cap since the tool
existed, but the ws handler dropped the param — UIs building on
cron.manage could not create run-N-times jobs. Forward it (digit
strings accepted, None keeps schedule-kind defaults). One-shot
relative schedules (bare 30m/2h) already flow through the schedule
string untouched.
