Fix API response parsing and remove /api prefix from backend routes

- Fixed chat-session-sidebar.tsx to check for 'success' field instead of 'status'
- Removed /api prefix from backend router to match frontend expectations
- Backend endpoints now directly accessible at /chat, /contracts, etc
- Frontend properly parses session list responses
