fix: load caller name and profile picture in call notification

Both CallController and EventNotificationConsumer now load the
caller's profile picture via Coil before showing the notification,
so the large icon displays the caller's avatar instead of being
empty. The caller name was already loaded from LocalCache but now
the bitmap accompanies it.
