Subject: [PATCH] feat(events): forward Picture, UserAbout and BusinessName
 webhook events

The dispatcher in pkg/whatsmeow/service/whatsmeow.go dropped three events
emitted by go.mau.fi/whatsmeow because the central switch had no case for
them, logging "Unhandled event" instead of forwarding them:

- events.Picture: a user's profile picture or a group's photo changes
  (JID, Author, Timestamp, Remove, PictureID).
- events.UserAbout: a user's about/status text changes (JID, Status,
  Timestamp).
- events.BusinessName: a contact's verified business name changes (JID,
  OldBusinessName, NewBusinessName).

Add the three handler cases in myEventHandler, the matching branches in
CallWebhook, and the PICTURE, USER_ABOUT and BUSINESS_NAME subscription
categories in pkg/internal/event_types so IsEventType accepts them.

The change is additive: existing subscribers are unaffected, and the new
events require opting in via the subscribe list (or ALL).
