Added CAPROVER-DEPLOYMENT-FIX.md with instructions for required environment variables to prevent 500 errors. Improved validation and fallback logic for SERVER_API_URL and API_BASE_URL in server-api.ts, route.ts, and next.config.mjs to handle missing or invalid values gracefully and log warnings instead of crashing.
Replaces hardcoded production API URLs with localhost defaults for local development in both server and client code. Updates Dockerfile to require API URLs via deployment environment variables. Improves ChatTable to use a batch endpoint for chats and unread counts, with backward compatibility. Adds an env.example file to document required environment variables. Updates next.config.mjs to use environment variables for backend API rewrites and image domains.
Introduces product selection and exclusion controls to both new and edit promotion forms, allowing promotions to target all, specific, or all-but-specific products. Adds a reusable ProductSelector component, updates promotion types to support new fields, and adjusts cookie max-age for authentication. Also adds two new business quotes.
