feat(accessibility): add screen reader support for chat list

Expose painted dialog rows as virtual accessibility children so
screen readers can navigate the chat list.

Each row reports: chat type, name, badges, status, last message
preview, delivery status, reactions, stories, and more.

Multi-column sub-items provide structured per-field access.
