Backend: enrich message reply data (include created_at and media_files) and ensure chat owners are treated as members; tighten/extend permission checks and message query filters; fix hub routers so moderators/tags routes are resolved before hub detail; accept hub id from request.data in hub permission/tag views; add PostHub serializer and expose hub_detail on posts.
Frontend: update generated API models (postHub, replyTo, members_detail, hub_detail); add hub-related pages/routes and components (HubCard, HubHeader, Tags) and a hub posts feed hook; rework message UI and composer to show richer reply previews (media thumbnails, timestamps), adjust video preload to metadata; add tag selection UI to PostComposer and wire hub tags fetching.
Also: minor UI/UX improvements and generated model exports updated to match backend changes.
Add a signal to keep direct-message chat name and icon in sync when a user updates their username or avatar, and register it in AppConfig.ready. Also initialize a DM chat's name/icon on creation from the other member's username/avatar if those fields are missing, saving only the changed fields.
Expanded chat backend with message reply, edit, delete, and reaction support in consumers and models. Updated routing to use chat_id. Added chat-related view stubs. On the frontend, introduced ChatLayout and ChatPage scaffolding, and routed protected routes through ChatLayout.
