Introduces backend/app/paths.py to centralize all key directory paths, allowing overrides via environment variables for local development. Updates all backend services and APIs to use these centralized paths instead of hardcoded values. Adds dev path override examples to backend/.env.example and updates .gitignore to exclude dev-data. Also changes frontend dev server port to 5274 and updates related scripts and CORS settings for consistency.
Introduces backend logic to determine server resource tier and block WordPress site creation on insufficient resources (lite tier). Adds ResourceTierContext and ResourceGate component to the frontend, displaying a UI warning and disabling creation actions when requirements are not met. Updates WordPress page and styles to integrate the new resource gating mechanism.
Moved and improved development helper scripts for better cross-platform support, including WSL and Docker. Updated backend login to accept username or email, and updated frontend login form accordingly. Enhanced backend and frontend dev server compatibility for WSL. Updated documentation for streamlined setup and usage.
