Investigate proxying Plausible script

[alyssadai]

Since adblockers can block Plausible, our current implementation of Plausible is likely undercounting user visits due to communication between JS apps and Plausible being blocked.

This affects all instances of our JS apps:

• public query tool
• public annotation tool
• BIC query tool

To get more accurate stats, Plausible documents a way to proxy it through e.g., NGINX to avoid cross-origin errors between our JS apps and Plausible. We could try this out on our cloud server to see how straightforward / maintainable this solution is using our Dockerized NGINX setup.
