♻️ Replace flume with tokio and share Matrix client infos to chats

- Remove of the flume dependency.
- Add the capability to share data provided by the Matrix client to the ChatsWindow. Indeed, until the 0.6 Dioxus
  release, each window runs in a separate virtual DOM so the context and Fermi states are completely seperate
  (cf. https://discord.com/channels/899851952891002890/1188206938215948378).
