fix(scheduled-tasks): lock modal dismiss while a save is in flight

Cancel, the header X, Escape, and overlay click all route through one guarded
onOpenChange that no-ops while submitting, and the footer Cancel is disabled
(cancelDisabled) — so an in-progress create/edit can't be abandoned mid-save and
lose its draft. submitting moves up to TaskModal so the guard can read it.
