The PR updates the OpenAPI title, refines protected-route loading styles, adds chat window states and placeholder components, and implements cursor-based message fetching through the chat store and service.

Changes

Chat message flow

Layer / File(s)	Summary
Paginated message fetching frontend/src/services/chatService.ts, frontend/src/stores/useChatStore.tsx, frontend/src/types/store.ts	The chat service and store now support 50-message cursor pagination, ownership mapping, prepended messages, and separate conversation and message loading flags.
Conversation selection wiring frontend/src/components/chat/sidebar/*, frontend/src/pages/ChatAppPage.tsx	Conversation cards fetch uncached messages. The sidebar and chat layout now render as siblings within SidebarProvider.
Chat window states and composition frontend/src/components/chat/layout/*	The chat window renders welcome, loading, and active conversation states with header, body, input, and skeleton components.

Authentication loading UI

Layer / File(s)	Summary
Protected-route loader styling frontend/src/components/auth/ProtectedRoute.tsx	The loader uses direct fixed-size styling with dark-mode text color and no unused cn import.

API branding

Layer / File(s)	Summary
OpenAPI title backend/src/swagger.json	The OpenAPI title changes from Moji to Chatify.
