feat(scheduler): slot gating + morning work-day gate

- _add_user_jobs now accepts config dict and skips disabled slots
- _get_briefing_enabled_users returns 3-tuple (user_id, tz, config)
- update_user_schedule passes config through to _add_user_jobs
- _run_slot_for_user skips morning slot on non-work days via profile.work_schedule
- Add tests for slot gating and work-day gate
