WhatsApp chat history import proceeds in parts

When a number from the WhatsApp Business app is connected to the panel, past chats are imported in parts. The import proceeds chat by chat; chats carrying hundreds of messages are split into parts and processed, and every chat completes on its own.

• Where the import stands is followed from the progress information on the channel card.
• When a part is left incomplete, a warning saying so stays on the card, and the status can be seen later as well.
