fix: read parent_id field from Evotor API and move VK products between albums on group change

- catalog.py: include parent_id as fallback for group_evotor_id (Evotor API returns parent_id instead of group/parentUuid)
- vk_sync.py: on product update, detect album change and call market.removeFromAlbum + market.addToAlbum to move product to the correct album
