Switch hub endpoints to use the hub `name` slug and update frontend routes/clients accordingly. Backend: HubViewSet now uses lookup_field='name'; PostViewSet list supports `sort=top` with vote_score annotation and time windows/custom ranges, and a new TopPostsCursorPagination was added. Frontend: routes changed from `/hub/:id` to `/h/:name`, the generated hubs API was updated from id->name, and the hub feed client accepts `sort`, `time`, `start`, and `end` params (query key updated). Also adds new homepage UI components (HeroSection, DroneSection) and navbar improvements (scroll state, auto-close mobile menu on route changes, and small icon/class tweaks).
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.
