Replace the free-form trigger-config form with a structured schedule editor built on an orthogonal cron model: separate frequency, time, and day-of-week/day-of-month dimensions map to and from cron expressions via a dedicated grammar and mapping layer, with validation and a human-readable describe() summary. The grammar suite drives the editor against a combinatorially generated corpus of 51,755 distinct cron expressions - every token form of every field, crossed - each judged against a reference robfig/cron v3 parser. Add a server-side /autopilot/cron-preview endpoint (plus schema and React Query hook) so the editor shows upcoming run times, and echo wildcard-carrying cron lists correctly instead of collapsing them. Supporting pieces: timezone-aware formatting helper, segmented-toggle and debounced-value utilities, a reworked time-input, and refreshed en/ja/ko/zh-Hans locale strings.
