Message Detail (Mobile): Missing Move to Folder icon

[computrav]

Describe the bug
Perhaps not totally a hug, but seems inconsistent with rest of UI functionality. When you're viewing a message there's no way to move the message to a folder:

To Reproduce
Steps to reproduce the behavior:

1. Open any message from the message list
2. Observe icons/functionality on the top bar

Expected behavior
An icon exists to move the message to a folder.

This works, but consider using the same component/interface that is used if you click the Move icon on a message in the message list (the updated one that now includes Recent and Favorited folders).
