[install] add NGINX reverse proxy to docker-compose setup

[MAHIRE-7]

Currently SigNoz docker-compose setup exposes the frontend directly.

It might be useful to add an NGINX reverse proxy service that:

Routes traffic to the frontend

Allows easy TLS configuration

Makes production deployment easier

Proposal

Add an optional docker-compose.yml with:

NGINX reverse proxy

Config file for routing to frontend

Documentation in deployment guide

I would like to work on this if maintainers think it is useful.

Hey @MAHIRE-7, thanks for letting us know! This is useful, but since it's not directly related to the SigNoz setup, I suggest we approach it differently. Instead of adding it to our docker-compose configuration, we could document it as a guide for configuring it alongside the default setup. That would be a good fit for our docs repo at https://github.com/signoz/signoz.io

Thanks for the suggestion! That makes sense. Instead of modifying the main docker-compose setup, I can prepare a guide explaining how to configure it alongside the default SigNoz setup.

We could also provide an optional docker-compose.nginx.yaml file so users can easily enable it with the default setup if they need NGINX. I can add the documentation and share it for the docs repo.
