Fix linting errors, server actions config, and chat history functionality

- Fixed switch clause declaration issue in app/actions.tsx by wrapping case block in curly braces
- Removed empty interface and empty object pattern in chat-history-client.tsx
- Added SERVER_ACTIONS_ALLOWED_ORIGINS environment variable support
- Updated next.config.mjs to read allowed origins from environment with fallback
- Fixed getChats function to properly filter by user_id and sort by created_at
- Ensured chat history is retained and displayed correctly in Supabase

All SQL migration files remain unchanged as requested.
