feat: cleaning tooltip, report photos, fix tech task creation, completion photos

- Calendar: hover tooltip on '🧹 убирается' shows who is cleaning (assignee name)
  fetched from active HK tasks on mount, updated via WS housekeeping_updated events
- HousekeepingPage: 'Сообщить о неисправности' now creates a real maintenance task
  in the DB (category=maintenance) + sends WS so TechnicalPage receives it instantly;
  photo upload added to the report form
- RoomContextMenu: photo upload added to tech task creation form (camera button,
  preview thumbnails); photos passed through to API on task creation
- TechnicalPage: selecting 'Выполнено' now opens CompletionModal with photo upload;
  technician can attach completion photos before confirming; if require_completion_photo
  setting is on — at least one photo is required
- Settings (HousekeepingPage plans tab): new toggle 'Обязательное фото при завершении
  тех. задачи' saved to housekeeping_settings.require_completion_photo (migration 027)
- Backend: housekeeping-settings updated with require_completion_photo field
