Subject: [PATCH] Fix: Add ensure_ascii=False to WhatsApp send payload

The send() payload contains user message content (msg.content) which
may include non-ASCII characters (e.g. CJK, German umlauts, emoji).

The auth frame and Discord heartbeat/identify payloads are left
unchanged as they only carry ASCII protocol fields.
