ScheduleStartPage now starts dateFrom/dateTo as null so the input shows the `ДД.ММ.ГГГГ - ДД.ММ.ГГГГ` placeholder Angular ships instead of pre-filling with the current week. The submit handler defaults to current-week range when the user submits without picking dates, preserving the legacy "find this week" UX. Same pattern as the onlineboard date fix.
