FastAPI trailing-slash redirects (307) were using http:// instead of https:// because uvicorn wasn't reading X-Forwarded-Proto from the reverse proxy. When Pangolin (TLS-terminating proxy) received the http:// redirect it returned 503, breaking all list endpoints (/events, /calendars, /settings, /projects, /people, /locations). Adding --proxy-headers makes uvicorn honour X-Forwarded-Proto so redirects use the correct scheme. --forwarded-allow-ips '*' trusts headers from any IP since nginx sits on the Docker bridge network.
