slotIndex is a per-department index of non-empty intervals, not a time. Merging all departments of a period by slotIndex and deriving the slot time from the first inserted lesson produced shifted times (e.g. Meltsov 10:00 shown at 11:45) depending on sync order. Group by lesson start minute instead so each department's real times are kept. Add debug logging for teacher schedule sync/build and debounce teacher search in picker.
