fix(docker): force HTTP/1.1 on frontend nginx upstream proxy

The frontend nginx config proxied to the backend without setting
proxy_http_version, so nginx used its default of HTTP/1.0 for the
upstream requests. Behind an HTTP/1.1-only proxy (e.g. an Istio/Envoy
service-mesh sidecar) those requests are rejected with HTTP 426 Upgrade
Required, breaking /api, /health, and /health_check.

Set proxy_http_version 1.1 explicitly on every proxy_pass block in both
default.conf.template (rendered into the production frontend image) and
nginx.conf. This is version-independent and keeps working regardless of
which nginx the image ships (the image pins nginx 1.28.0, whose upstream
default is still HTTP/1.0).

Verified with the pinned nginx image in front of an HTTP/1.1-only mock
upstream: /api, /health, /health_check return 200 and nginx forwards
upstream as HTTP/1.1 (was 426 / HTTP/1.0 before the fix).

Fixes #9010
