Interview scheduling: clearer break spacing and easy time removal

Setting interview availability now shows exactly how your choices shape the calendar. Pick a gap between calls (5, 10, 15 or 30 minutes) and the preview and saved times reflect it, so you can see the breathing room people get between interviews.

When plans change, removing saved times is no longer one call at a time. Each day has a remove option, and one button clears every open time on the schedule after a quick confirmation. Times that people have already booked stay put until their sessions are cancelled.

The warning you see when new hours overlap saved times now explains what to do: remove the saved times first, then add the new hours.
