📄 Description

Add Chat.id as a secondary sort key to all paginated chat queries that use offset/limit pagination. When multiple chats share the same updated_at timestamp, the database does not guarantee a stable order across page boundaries, causing chats to appear on multiple pages.

This produces duplicate keys in the Svelte sidebar each-block (each_key_duplicate error). Adding Chat.id as a tiebreaker ensures fully deterministic ordering.

Extends the fix from #22383 (which addressed get_chat_ids_by_model_id) to all remaining paginated chat queries.
