feat: dockerized server for simulating js-waku in headless browser

[adklempner]

Description

We need to validate that js-waku browser tests can be successfully integrated into DST's simulation environment. Before implementing the full API, we should create a proof-of-concept with minimal functionality to ensure the approach is viable.

User Story

As a DST engineer, I want to run a simple end-to-end test using js-waku in a containerized browser environment, so that I can confirm our simulation infrastructure can integrate with js-waku browser tests before more extensive development is done.

Proposed Solution / Feature Design

Create a minimal proof-of-concept implementation with:

1. A basic web application running a js-waku node with limited functionality
2. A server exposing a small subset of the nwaku REST API (3-5 endpoints)
3. Docker packaging that allows the solution to be run in DST's simulation environment
4. Documentation for running a simple test case (e.g., connecting to peers, sending/receiving a basic message)

This PoC should focus on validating the core integration rather than implementing all features. Success criteria is DST being able to run at least one simple end-to-end test in their simulation environment.

Notes

• Implementation should prioritize compatibility with DST's existing simulation infrastructure
• Only implement enough API functionality to validate the approach (connect, peer info, send/receive on one protocol)
• Include instructions for DST team on how to integrate and run the test
• Gather feedback to inform the complete implementation
