In production, CORS_ORIGINS now defaults to UMBRA_URL so deployers only
need to set the external URL once. In development it defaults to
http://localhost:5173 (Vite dev server). Explicit CORS_ORIGINS env var
is still respected as an override for multi-origin or custom setups.
This means a production .env only needs: ENVIRONMENT, SECRET_KEY,
UMBRA_URL, and DB credentials. COOKIE_SECURE and CORS_ORIGINS both
auto-derive.
