feat: task problem/solution split + maintenance icons on rooms/calendar

- TechnicalPage: redesign task cards with separate "Задача" and "Решение" sections
  - "Задача": problem description + problem photos (editable before done)
  - "Решение": technician resolution comment + resolution photos (green section)
  - Resolution comment in CompletionModal now saves to resolution_notes field
  - Resolution photos save to resolution_photos (no longer mixed with problem photos)
- RoomModal history tab: maintenance entries show separate problem/resolution sections
- Backend: add resolution_notes, resolution_photos to PATCH allowed fields
- Migration 029: resolution_notes TEXT + resolution_photos TEXT[] columns
- RoomsPage: load active maintenance tasks, show 🔧 неисправность badge on room cards
- CalendarPage: load active maintenance tasks, show 🔧 неиспр. label in calendar row
- BookingCalendar: activeMaintenance prop, WS handler updates maintenance set on task changes
- CalendarPage WS: handle housekeeping_task_created to update activeMaintenance set
