feat(message-list): add Avatar to MessageListContent

[shamim-emon]

• Fixes Add avatar to message list content #9822

Implementation Highlights

• Contact / Avatar Retrieval

  • Updated ContactRepository interface to expose a getPhotoUri(emailAddress: String): Uri?. (Added methods)
  • In CachingContactRepository, implemented this method to extract photoUri from a cached contact record.

• Dependency & Build Updates

  • Added dependencies for avatar feature modules (feature.account.avatar.api and feature.account.avatar.impl) in legacy/ui/legacy/build.gradle.kts.

• Preview / Debug UI

  • In MessageItemContentPreview.kt, updated the preview composables to include fake avatar / monogram providers so that previews render avatars.

• ContactPhotoLoader Cleanup

  • Removed a redundant local getPhotoUri(...) implementation, redirecting to the unified ContactRepository.getPhotoUri(...). (Simplifies and centralizes contact-photo logic) .

• Adapter / Fragment Wiring

  • MessageListAdapter now accepts ContactRepository and AvatarMonogramCreator and passes them down to ComposableMessageViewHolder.
  • In MessageListFragment, injected contactRepository and avatarMonogramCreator and passed them into the adapter construction.
  • ComposableMessageViewHolder was updated to accept and use an onAvatarClick callback alongside the existing onClick / onLongClick.
  • When binding, the composable view is given contact + avatar monogram info so it can render the correct avatar.

NOTE: This feature is behind feature flag: use_compose_for_message_list_items.

In contrast to the old image loader, landscapist using coil is able to load the contact picture directly from the contact photo uri.

So instead of handling bitmaps we just need to provide the uri similarly to ContactPhotoLoader.getPhotoUri. Ideally this is either a new method for the ContactRepository or a layer on top that just extracts the photo uri from the contact for a given address.

Instead of reusing the current placeholder, the new design uses two characters from the contact. So the placeholder could be build as composable and avoid the bitmap manipulation.

Box(contentAlignment = Alignment.Center) {
    TextTitleSmall(text = monogram)
}

Thank you. Just some small things left. I think for the next iteration, we need to find a better way to provide details of the design, like measurements, color and size values.

👍

Optional: If you like you could also wire the click handling to trigger the message item selection when the avatar is clicked.

LGTM and thank you!
