fix: replace broken Postiz reverse proxy with iframe embed 

The reverse proxy couldn't work for a Next.js SPA — it caused double
space prefix in redirects and couldn't handle /_next/* static assets.
Switch to iframe approach with demo.rsocials.online directly. Fix
template literal bugs where getSchedulerUrl() was passed as a string
literal instead of being evaluated.
