fix WhatsApp group chat support and self-message handling

Browse Source 
Bridge: allow fromMe messages in groups, include participant field in
message queue, bind to 0.0.0.0 for network access, QR served as HTML.

Adapter: process registered group messages (route to Claude), extract
participant for user identification, fix unbound 'phone' variable.

Tested end-to-end: WhatsApp group chat with Claude working. 442 tests pass.
