fix: housekeeping tasks not appearing + add history tab + fix task type

- Fix root cause: CalendarPage created tasks with type='regular' which violated DB CHECK constraint (allowed: cleaning/turnover/inspection/maintenance/amenities) → INSERT silently failed. Fixed to type='cleaning'.
- Fix: HousekeepingPage now loads ALL active tasks (status=active = pending+in_progress) without date filter — tasks appear regardless of when they were created
- Backend: support ?status=active filter (translates to IN ('pending','in_progress'))
- Add "История" tab in HousekeepingPage: shows completed tasks for a selected date with prev/next navigation, assignee and completion time displayed
- WS handler: when task becomes done, move it from active list instead of keeping in place
