## Context
Self-hosting on a LAN host (e.g. http://helicone.homelab.lan): lots of hard-coded `YOUR_HOST` and `helicone.ai` references in the codebase, so the deployment only works on YOUR_HOST or the managed cloud.

## Verified resolution
Maintainer tomharmon confirmed a team PR was up for this; maintainer devinat1 merged PR #4230 replacing the hard-coded references with env-var-driven configuration (reporter torarnv confirmed). The reporter also asked for a published Docker image since building locally is heavy on a NAS.
