feat: adapt shortcuts to Compose conversation operations sheet

Upstream migrated the conversation bottom dialog to a Compose
ModalBottomSheet. Adapt our shortcut features to the new architecture:

- Add AddToHomeScreen action to ConversationOpsAction sealed class
- Add "Add to home screen" menu item in ConversationOperationsSheet
- Wire handler in ConversationsListActivity.handleConversationOpsAction
- Fix back-stack: pass KEY_INTERNAL_USER_ID to ConversationsListActivity
  via intent so it reads the correct user from DB instead of stale cache
