Each office sets VITE_CLOUDFLARE_HOST and CLOUDFLARE_HOST in their
local .env files instead of hardcoding the subdomain in source code.

External browsers were hitting localhost:5000 instead of going through
nginx. VITE_API_BASE_URL_BACKEND is now empty so all API calls use
relative /api/ paths that nginx proxies to the backend. Also adds
https://communitydentistsoflowell.mydentalofficemanagement.com to
FRONTEND_URLS for CORS. Updated .env.example to match so setup from
template doesn't silently revert this fix.
