Pull request overview

This PR adds initial Matrix (client-server) support to the Threadlet client, shifting core chat concepts from the existing forum/post/message model toward Matrix rooms and events, along with a new login/register flow and UI updates.

Changes:

• Introduces a Matrix client wrapper and boot flow (login/register, start sync, room list + room views).
• Adds event rendering for common Matrix message/event types (text, image, file, audio, video, notice, emote, room name) plus an unknown-event fallback.
• Updates UI layout and components (member list, context menus, room creation/invites) and replaces message list plumbing with an event list.

• This file still imports Threadlet/Post message types, api, and Message, but the implementation now only operates on MatrixEvent and renderEvent(). Remove unused imports to avoid confusion and keep the module focused on Matrix events.
