Description

Migrate MessageListFragment from the legacy XML-based rendering to use the new MessageListScreenRenderer backed by Compose. This includes creating the new fragment layout with a ComposeView, registering the renderer in the DI module, extracting side effect handler factories, adding the AllConfigurationsReadySideEffect, and cleaning up the fragment.

Acceptance Criteria

• MessageListFragment uses the new ComposeView-based layout (new_message_list_fragment.xml).
• MessageListScreenRenderer is registered in FeatureMessageListModule.
• Side effect handler factories are extracted to a dedicated MessageListSideEffectsModule.
• AllConfigurationsReadySideEffect handles readiness transitions in the WarmingUp state.
• MessageListMetadata.isReady property simplifies state logic.
• MessageListStateMachine enhanced with logging and transaction history dump for debugging.
• Fragment is cleaned up from legacy rendering code.
