[monorepo] switch all output file reads to clsi-nginx (#31691)

* [monorepo] switch all output file reads to clsi-nginx

* [clsi-lb] allow gallery download requests

* [terraform] clsi: use nginx.conf from clsi service

* [clsi] fix flakey tests

* [clsi] replace alias with rewrite and root in nginx config

* [k8s] clsi-lb: expose download port on internal service

* [web] add explicit endpoint for downloading all output files

Serve the output.zip endpoint from clsi.

* [clsi] fix regex for latexqc submission ids

Previously, we only handled template submission ids.
