[LHF-03] Hardcoded Microservice Endpoint Bindings

[sheepdestroyer]

Location

router/main.py (inside sync_adaptive_router_roster, check_http_endpoint, get_dashboard, proxy_memory, proxy_models, etc.)

Problem Description

Core target URLs (LiteLLM at http://127.0.0.1:4000/, Llama.cpp at http://127.0.0.1:8080/health, Langfuse at http://127.0.0.1:3001) are hardcoded directly inside logic checks, reducing deployment agility across varied rootless Podman networks where microservices run on separate hostnames (e.g. http://litellm:4000).

Fix Overview

Extract the endpoint bases into environment variable parameters while assigning safe fallback constants near the top of the file.

Proposed Implementation Steps

1. Define global configuration variables near the top of router/main.py:

   LITELLM_URL = os.getenv("LITELLM_ADMIN_URL", "http://127.0.0.1:4000")
   LLAMA_SERVER_URL = os.getenv("LLAMA_SERVER_URL", "http://127.0.0.1:8080")
   LANGFUSE_URL = os.getenv("LANGFUSE_URL", "http://127.0.0.1:3001")

2. Replace all hardcoded occurrences with these constants throughout the file.
