fix(docker): drop undefined $PYTHONPATH prefix in production Dockerfiles#192

Conversation
The api and conserver Dockerfiles set PYTHONPATH as
`${PYTHONPATH}:/app/...`, but the base image (python:3.12-slim) never sets
PYTHONPATH, so the variable was undefined — BuildKit emitted an UndefinedVar
warning and the value carried a stray leading colon (an empty/cwd path entry).
Drop the prefix. The listed directories are unchanged, and `/app` is already
among them, so the implicit current-dir entry was redundant — no behavior
change, just a clean PYTHONPATH and no warning.

The api and conserver Dockerfiles set
PYTHONPATHas${PYTHONPATH}:/app/..., but the base image (python:3.12-slim) never definesPYTHONPATH. BuildKit therefore emits anUndefinedVar: Usage of undefined variable '$PYTHONPATH'warning on every build, and the resulting value carries a stray leading colon (an empty path entry = current dir).This drops the
${PYTHONPATH}:prefix:No behavior change: the listed directories are identical, and
/appis already among them, so the implicit current-dir entry was redundant. The dev/test image (docker/Dockerfile) already uses this prefix-free form.🤖 Generated with Claude Code
