Added reliable scheduled starts and hard-stop end times
Pro hosts can now prepare an agenda around the real event clock. Schedule a segment to start at a specific time, choose a fixed End at time when a hard stop matters, and let the Room keep that timing even when Host and Display are not left open.
- Use Manual or Scheduled starts with either a duration or a fixed End at time
- Show each planned time in the Room's time zone before publishing the agenda
- Catch past times, overlapping scheduled segments, and incompatible linked starts before they can go live
- Review an expired saved schedule before reopening a Room, instead of silently changing or starting it
