mv_layout_velocity (powers best_layouts, #113) refreshed only via manual refresh_layout_velocity() → prod data silently went stale. Add Celery task mirroring refresh_quarter_price_index, register in celery_app include, add weekly beat entry (Sun 03:00 MSK, outside the monday heavy-refresh cluster). Closes #1666

"""Celery task: refresh mv_layout_velocity (питает «лучшие планировки» best_layouts).
|
||
|
||
Scheduled via hardcoded beat entry in workers/beat_schedule.py:
|
||
'refresh-layout-velocity' — weekly on Sunday at 03:00 MSK.
|
||
Стоит в «ночном» окне воскресенья, отдельно от monday-кластера тяжёлых
|
||
site_finder-рефрешей (supply-layers / ird / gknspecial / cbr и т.д.), чтобы
|
||
не конкурировать с ними за БД/CPU.
|
||
|
||
Issue: #1666 (рефреш не был подключён в beat → данные best_layouts молча
|
||
устаревали в проде). MV-источник: #113 (PR B, mv_layout_velocity → best_layouts).
