N/A — maintainer-directed repair; no linked issue required for this PR.

Description

Automation schedules saved today’s UTC offset and could shift at daylight-saving changes. New schedules use local cron fields plus an IANA zone when supported. Verify the echoed zone and fall back to the UTC contract when it was not persisted. Previews use the saved zone, and offset-free server timestamps parse as UTC. Existing schedules without a zone keep their UTC contract on edit. The self-hosted scheduler uses additive timezone, date and expiration rules.

Current main is merged, retaining Automation draft review/focus behavior.

Testing Evidence (REQUIRED)

116 focused frontend tests and 9 self-hosted scheduler tests passed, including London/New York DST changes, missing/repeated local hours, UTC fallback, persisted zones and editing legacy schedules on a timezone-capable server. Type-check, focused ESLint/Prettier and git diff --check passed. Existing SchedulePicker/shared primitives and semantic tokens retained. No full packaged-app time-zone/theme matrix was run. The matching production server change must be deployed before this is released.

Automated checks only; manual app testing is pending.
