📄 Description

Some databases contain chat records where 'history' or 'messages' are stored as lists instead of dicts. This causes an AttributeError ('list' object has no attribute 'items') during the 8452d01d26d7_add_chat_message_table migration.

Add isinstance checks to skip chat records with unexpected data shapes gracefully, matching the existing pattern used for individual message validation.
